Top Genetics Expert: Japan's path closely resembles Chernobyl's - "Very, very major dis... - 0 views

  • This week’s guest is Wladimir Wertelecki, the founder and chairman of the Department of Medical Genetics and Birth Defects Center of the University of South Alabama, in the U.S. Prior to his training in Medical Genetics at Harvard University Medical School, Dr. Wertelecki trained in Pediatrics at St. Louis Children’s Hospital, Washington University. Later, he served as Senior Surgeon, U.S. Public Health Commission Corps at the Epidemiology Branch of the National Cancer Institute [...] He has extensively studied the effects of the radiation released by the Chernobyl meltdown on public health, particularly in children [...]
  • Wertelecki: I did give lectures in Tokyo recently and I met people from a variety of Universities that attended these events. My sense is that the path followed in Japan closely resembles the path that evolved after Chernobyl. And there are more regrettables than nonregrettables. It seems like frankly it’s difficult to understand what’s going on and what’s not going on. From my point of view the absolute priority is women of reproductive age… No registry of pregnant women as far as I know… very little concentration on these aspects… everything is concentrated on cancer…children beyond the scope of thyroid cancer are very important…
  • Wertelecki: There’s a team of expert son birds and ornithology form France, very distinguished Danish ornithologist who found in Chernobyl area very, very major disturbing findings that exactly the same is happening in Fukushima. In other words these birds cannot migrate because they become exhausted… they find microcephaly just like we do, they find all kind of instability like random spotted changes to fur, which are local mutations of course on so on and so on.

Why the Fukushima disaster is worse than Chernobyl [29Aug11][ - 0 views

  • This nation has recovered from worse natural – and manmade – catastrophes. But it is the triple meltdown and its aftermath at the Fukushima nuclear power plant 40km down the coast from Soma that has elevated Japan into unknown, and unknowable, terrain. Across the northeast, millions of people are living with its consequences and searching for a consensus on a safe radiation level that does not exist. Experts give bewilderingly different assessments of its dangers.
  • Some scientists say Fukushima is worse than the 1986 Chernobyl accident, with which it shares a maximum level-7 rating on the sliding scale of nuclear disasters. One of the most prominent of them is Dr Helen Caldicott, an Australian physician and long time anti-nuclear activist who warns of "horrors to come" in Fukushima.
  • Chris Busby, a professor at the University of Ulster known for his alarmist views, generated controversy during a Japan visit last month when he said the disaster would result in more than 1 million deaths. "Fukushima is still boiling its radionuclides all over Japan," he said. "Chernobyl went up in one go. So Fukushima is worse."

  • On the other side of the nuclear fence are the industry friendly scientists who insist that the crisis is under control and radiation levels are mostly safe. "I believe the government and Tokyo Electric Power [Tepco, the plant's operator] are doing their best," said Naoto Sekimura, vice-dean of the Graduate School of Engineering at the University of Tokyo. Mr Sekimura initially advised residents near the plant that a radioactive disaster was "unlikely" and that they should stay "calm", an assessment he has since had to reverse.
  • Slowly, steadily, and often well behind the curve, the government has worsened its prognosis of the disaster. Last Friday, scientists affiliated with the Nuclear and Industrial Safety Agency said the plant had released 15,000 terabecquerels of cancer-causing Cesium, equivalent to about 168 times the 1945 atomic bombing of Hiroshima, the event that ushered in the nuclear age. (Professor Busby says the release is at least 72,000 times worse than Hiroshima).
  • Caught in a blizzard of often conflicting information, many Japanese instinctively grope for the beacons they know. Mr Ichida and his colleagues say they no longer trust the nuclear industry or the officials who assured them the Fukushima plant was safe. But they have faith in government radiation testing and believe they will soon be allowed back to sea.
  • That's a mistake, say sceptics, who note a consistent pattern of official lying, foot-dragging and concealment. Last week, officials finally admitted something long argued by its critics: that thousands of people with homes near the crippled nuclear plant may not be able to return for a generation or more. "We can't rule out the possibility that there will be some areas where it will be hard for residents to return to their homes for a long time," said Yukio Edano, the government's top government spokesman.
  • hundreds of former residents from Futaba and Okuma, the towns nearest the plant, were allowed to visit their homes – perhaps for the last time – to pick up belongings. Wearing masks and radiation suits, they drove through the 20km contaminated zone around the plant, where hundreds of animals have died and rotted in the sun, to find kitchens and living rooms partly reclaimed by nature.
  • It is the fate of people outside the evacuation zones, however, that causes the most bitter controversy. Parents in Fukushima City, 63km from the plant, have banded together to demand that the government do more to protect about 100,000 children. Schools have banned soccer and other outdoor sports. Windows are kept closed. "We've just been left to fend for ourselves," says Machiko Sato, a grandmother who lives in the city. "It makes me so angry."
  • Many parents have already sent their children to live with relatives or friends hundreds of kilometres away. Some want the government to evacuate the entire two million population of Fukushima Prefecture. "They're demanding the right to be able to evacuate," says anti-nuclear activist Aileen Mioko Smith, who works with the parents. "In other words, if they evacuate they want the government to support them."
  • Aid Fukushima: The UN's Office for the Co-ordination of Humanitarian Affairs reported bilateral aid worth $95m Chernobyl: 12 years after the disaster, the then Ukrainian president, Leonid Kuchma, complained that his country was still waiting for international help.
  • But many experts warn that the crisis is just beginning. Professor Tim Mousseau, a biological scientist who has spent more than a decade researching the genetic impact of radiation around Chernobyl, says he worries that many people in Fukushima are "burying their heads in the sand." His Chernobyl research concluded that biodiversity and the numbers of insects and spiders had shrunk inside the irradiated zone, and the bird population showed evidence of genetic defects, including smaller brain sizes.
  • "The truth is that we don't have sufficient data to provide accurate information on the long-term impact," he says. "What we can say, though, is that there are very likely to be very significant long-term health impact from prolonged exposure."
  • Economic cost Fukushima: Japan has estimated it will cost as much as £188bn to rebuild following the earthquake, tsunami and nuclear crisis. Chernobyl There are a number of estimates of the economic impact, but thetotal cost is thought to be about £144bn.
  • Safety Fukushima: workers are allowed to operate in the crippled plant up to a dose of 250mSv (millisieverts). Chernobyl: People exposed to 350mSv were relocated. In most countries the maximum annual dosage for a worker is 20mSv. The allowed dose for someone living close to a nuclear plant is 1mSv a year.
  • Death toll Fukushima: Two workers died inside the plant. Some scientists predict that one million lives will be lost to cancer. Chernobyl: It is difficult to say how many people died on the day of the disaster because of state security, but Greenpeace estimates that 200,000 have died from radiation-linked cancers in the 25 years since the accident.
  • Exclusion zone Fukushima: Tokyo initially ordered a 20km radius exclusion zone around the plant Chernobyl: The initial radius of the Chernobyl zone was set at 30km – 25 years later it is still largely in place.
  • Compensation Fukushima: Tepco's share price has collapsed since the disaster largely because of the amount it will need to pay out, about £10,000 a person Chernobyl: Not a lot. It has been reported that Armenian victims of the disaster were offered about £6 each in 1986
  • So far, at least, the authorities say that is not necessary. The official line is that the accident at the plant is winding down and radiation levels outside of the exclusion zone and designated "hot spots" are safe.
  • Japan has been slow to admit the scale of the meltdown. But now the truth is coming out. David McNeill reports from Soma City

First Laser Made of Living Cells Has Arrived [16Jun11] - 0 views

  • In an article published in Nature Photonics, researchers Malte Gather and Seok Hyun Yun describe how a solution made from GFP was used in combination with a mirrored chamber to create a laser. From this preliminary test, Gather and Yun were able to determine how much GFP was required to create the laser light. Using this result, they then moved ahead to genetically engineer mammalian cells that could express the GFP at the required levels.
  • The researchers report that they were able to create bright laser pulses that lasted a few nanoseconds with a single cell. Amazingly the cells were not damaged during the production of the laser light but were able to withstand hundreds of pulses. Furthermore, the spherical shape of the cell itself acted as a lens “refocusing the light and inducing emission of laser light at lower energy levels than required for the solution-based device.”
  • Although there are no immediate plans to use this technology, the erosion of the barrier between optical technologies and biology could open many doors in therapy and research. Gather tells PhysOrg.com that they “hope to be able to implant a structure equivalent to the mirrored chamber right into a cell, which would [sic] the next milestone in this research."

(Part 2) Professor Tatsuhiko Kodama of Tokyo University Tells the Politicians: "What Ar... - 0 views

  • Professor Kodama is the head of the Radioisotope Center at the University of Tokyo.Professor Kodama's anger is now directed toward the government's non-action to protect people, especially children and young mothers, from internal radiation exposure. His specialty is internal medicine using radioisotope, so he says he has done the intense research on internal radiation:
  • I have been in charge of antibody drugs at the Cabinet Office since Mr. Obuchi was the prime minister [1998-]. We put radioisotopes to antibody drugs to treat cancer. In other words, my job is to inject radioisotopes into human bodies, so my utmost concern is the internal radiation exposure and that is what I have been studying intensely.
  • The biggest problem of internal radiation is cancer. How does cancer happen? Because radiation cuts DNA strands. As you know, DNA is in a double helix. When it is in a double helix it is extremely stable. However, when a cell divides, the double helix becomes single strands, doubles and becomes 4 strands. This stage is the most vulnerable.
  • ...11 more annotations...
  • Therefore, the fetuses and small children, with cells that rapidly divide, are most susceptible to radiation danger. Even for adults, there are cells that rapidly divide such as hair, blood cells and intestinal epitheria, and they can be damaged by radiation.Let me give you an example of what we know about internal radiation.
  • One genetic mutation does not cause cancer. After the initial hit by radiation, it needs a different trigger for a cell to mutate into a cancer cell, which is called "driver mutation" or "passenger mutation". (For details please refer to the attached document about the cases in Chernobyl and cesium.)Alpha radiation is most famous. I was startled when I learned of a professor at Tokyo University who said it was safe to drink plutonium.
  • Alpha radiation is the most dangerous radiation. It causes thorotrast liver damage, as we, liver specialists, know very well.Internal radiation is referred to as such-and-such millisieverts, but it is utterly meaningless. Iodine-131 goes to thyroid gland, and thorotrast goes to liver, and cesium goes to urothelium and urinary bladder. Whole body scan is utterly meaningless unless you look at these parts in the body where radiation accumulates.
  • Thorotrast was a contrast medium used in Germany since 1890. It was used in Japan since 1930, but it was found that 25 to 30% of people developed liver cancer 20 to 30 years later.Why does it take so long before cancer develops? Thorotrast is an alpha-radiation nuclide. Alpha radiation injures nearby cells, and the DNA that is harmed most is P53. We now know, thanks to genome science, the entire sequence of human DNA. However, there are 3 million locations on the DNA that are different from person to person. So today, it doesn't make sense at all to proceed as if all humans are the same. The basic principle should be the "personal life medicine" when we look at internal radiation - which DNA is damaged, and what kind of change is taking place.
  • In case of thorotrast, it is proven that P53 is damaged in the first stage, and it takes 20 to 30 years for the 2nd, 3rd mutations to occur, causing liver cancer and leukemia.About iodine-131. As you know, iodine accumulates in thyroid gland, and that is most noticeable during the formative phase of thyroid gland, i.e. in small children.
  • However, when the first researcher in Ukraine was saying in 1991 "There are an increasing number of thyroid cancer", researchers in Japan and the US were publishing articles in Nature magazine saying "There is no causal relationship between the radiation and thyroid cancer." Why did they say that? Because there was no data prior to 1986, there was no statistical significance.
  • The statistical significance was finally noted 20 years later. Why? Because the peak that started in 1986 disappeared. So even without the data prior to 1986, the occurrence of thyroid cancer and radiation exposure from Chernobyl had the causal relationship. Epidemiological proof is very difficult. It is impossible to prove until all the cases are done.Therefore, from the viewpoint of "protecting our children" a completely different approach is required.
  • Dr. Shoji Fukushima from a national institution called Japan Bioassay Research Center, which researches health effects of chemical compounds, has been studying diseases involving urinary tract since the Chernobyl accident.
  • Dr. Fukushima and doctors in Ukraine studied parts of bladders removed during more than 500 cases of prostatic hypertrophy surgery. They found out that in the highly contaminated area where 6Bq/liter was detected in urine, there was a high frequency of mutation of p53 though 6Bq may sound minuscule.
  • They also noticed many cases of proliferative precancerous conditions, which we assume was due to the activation of p38 MAP kinase and the signal called "NF-kappa B," leading inevitably to proliferative cystitis, with carcinoma in situ occurring with considerable frequency.Knowing this, I was astounded to hear the report that 2 to 13Bq/liter [of radioactive cesium] was detected from the breast milk of seven mothers in Fukushima.(to be continued in Part 3.)
  • When radioactive materials were detected from the breast milk, what did the government and government researchers say? "No need to worry. No immediate effect on health of the babies."Professor Kodama is saying that by the time we have proof that there is a causal relationship between internal radiation exposure (however small) and cancer, it may be too late.Thorotrast is a suspension containing the radioactive particles of thorium dioxide.

    Japanese Professor's testimony on July 27, here is an excerpt from pt 1: Professor Tatsuhiko Kodama is the head of the Radioisotope Center at the University of Tokyo. On July 27, he appeared as a witness to give testimony to the Committee on Welfare and Labor in Japan's Lower House in the Diet. Remember Professor Kosako, also from the University of Tokyo, who resigned in protest as special advisor to the prime minister over the 20 millisievert/year radiation limit for school children? There are more gutsy researchers at Todai (Tokyo University) - the supreme school for the "establishment" - than I thought. Professor Kodama literally shouted at the politicians in the committee, "What the hell are you doing?" He was of course referring to the pathetic response by the national government in dealing with the nuclear crisis, particularly when it comes to protecting children. Part two:

Fukushima radiation alarms doctors [18Aug11] - 0 views

  • Scientists and doctors are calling for a new national policy in Japan that mandates the testing of food, soil, water, and the air for radioactivity still being emitted from Fukushima's heavily damaged Daiichi nuclear power plant."How much radioactive materials have been released from the plant?" asked Dr Tatsuhiko Kodama, a professor at the Research Centre for Advanced Science and Technology and Director of the University of Tokyo's Radioisotope Centre, in a July 27 speech to the Committee of Health, Labour and Welfare at Japan's House of Representatives. "The government and TEPCO have not reported the total amount of the released radioactivity yet," said Kodama, who believes things are far worse than even the recent detection of extremely high radiation levels at the plant. There is widespread concern in Japan about a general lack of government monitoring for radiation, which has caused people to begin their own independent monitoring, which are also finding disturbingly high levels of radiation. Kodama's centre, using 27 facilities to measure radiation across the country, has been closely monitoring the situation at Fukushima - and their findings are alarming.According to Dr Kodama, the total amount of radiation released over a period of more than five months from the ongoing Fukushima nuclear disaster is the equivalent to more than 29 "Hiroshima-type atomic bombs" and the amount of uranium released "is equivalent to 20" Hiroshima bombs.
  • Kodama, along with other scientists, is concerned about the ongoing crisis resulting from the Fukushima situation, as well as what he believes to be inadequate government reaction, and believes the government needs to begin a large-scale response in order to begin decontaminating affected areas.Distrust of the Japanese government's response to the nuclear disaster is now common among people living in the effected prefectures, and people are concerned about their health.Recent readings taken at the plant are alarming.When on August 2nd readings of 10,000 millisieverts (10 sieverts) of radioactivity per hour were detected at the plant, Japan's science ministry said that level of dose is fatal to humans, and is enough radiation to kill a person within one to two weeks after the exposure. 10,000 millisieverts (mSv) is the equivalent of approximately 100,000 chest x-rays.
  • t is an amount 250 per cent higher than levels recorded at the plant in March after it was heavily damaged by the earthquake and ensuing tsunami. The operator of Japan's crippled Fukushima Daiichi nuclear power plant, Tokyo Electric Power Company (TEPCO), that took the reading, used equipment to measure radiation from a distance, and was unable to ascertain the exact level because the device's maximum reading is only 10,000 mSv. TEPCO also detected 1,000 millisieverts (mSv) per hour in debris outside the plant, as well as finding 4,000 mSv per hour inside one of the reactor buildings.

  • he Fukushima disaster has been rated as a "level seven" on the International Nuclear and Radiological Event Scale (INES). This level, the highest, is the same as the Chernobyl nuclear disaster in 1986, and is defined by the scale as: "[A] major release of radioactive material with widespread health and environmental effects requiring implementation of planned and extended countermeasures."The Fukushima and Chernobyl disasters are the only nuclear accidents to have been rated level seven on the scale, which is intended to be logarithmic, similar to the scale used to describe the comparative magnitude of earthquakes. Each increasing level represents an accident approximately ten times more severe than the previous level.
  • Doctors in Japan are already treating patients suffering health effects they attribute to radiation from the ongoing nuclear disaster."We have begun to see increased nosebleeds, stubborn cases of diarrhoea, and flu-like symptoms in children," Dr Yuko Yanagisawa, a physician at Funabashi Futawa Hospital in Chiba Prefecture, told Al Jazeera.
  • r Helen Caldicott, the founding president of Physicians for Social Responsibility, a group that was awarded the Nobel Peace Prize in 1985, is equally concerned about the health effects from Japan's nuclear disaster."Radioactive elements get into the testicles and ovaries, and these cause genetic disease like diabetes, cystic fibrosis, and mental retardation," she told Al Jazeera. "There are 2,600 of these diseases that get into our genes and are passed from generation to generation, forever."
  • Al Jazeera's Aela Callan, reporting from Japan's Ibaraki prefecture, said of the recently detected high radiation readings: "It is now looking more likely that this area has been this radioactive since the earthquake and tsunami, but no one realised until now."Workers at Fukushima are only allowed to be exposed to 250 mSv of ionising radiation per year.
  • radioactive cesium exceeding the government limit was detected in processed tea made in Tochigi City, about 160km from the troubled Fukushima Daiichi nuclear plant, according to the Tochigi Prefectural Government, who said radioactive cesium was detected in tea processed from leaves harvested in the city in early July. The level is more than 3 times the provisional government limit.
  • anagisawa's hospital is located approximately 200km from Fukushima, so the health problems she is seeing that she attributes to radiation exposure causes her to be concerned by what she believes to be a grossly inadequate response from the government.From her perspective, the only thing the government has done is to, on April 25, raise the acceptable radiation exposure limit for children from 1 mSv/year to 20 mSv/year.
  • This has caused controversy, from the medical point of view," Yanagisawa told Al Jazeera. "This is certainly an issue that involves both personal internal exposures as well as low-dose exposures."Junichi Sato, Greenpeace Japan Executive Director, said: "It is utterly outrageous to raise the exposure levels for children to twenty times the maximum limit for adults."
  • The Japanese government cannot simply increase safety limits for the sake of political convenience or to give the impression of normality."Authoritative current estimates of the health effects of low-dose ionizing radiation are published in the Biological Effects of Ionising Radiation VII (BEIR VII) report from the US National Academy of Sciences.
  • he report reflects the substantial weight of scientific evidence proving there is no exposure to ionizing radiation that is risk-free. The BEIR VII estimates that each 1 mSv of radiation is associated with an increased risk of all forms of cancer other than leukemia of about 1-in-10,000; an increased risk of leukemia of about 1-in-100,000; and a 1-in-17,500 increased risk of cancer death.
  • She attributes the symptoms to radiation exposure, and added: "We are encountering new situations we cannot explain with the body of knowledge we have relied upon up until now.""The situation at the Daiichi Nuclear facility in Fukushima has not yet been fully stabilised, and we can't yet see an end in sight," Yanagisawa said. "Because the nuclear material has not yet been encapsulated, radiation continues to stream into the environment."
  • So far, the only cases of acute radiation exposure have involved TEPCO workers at the stricken plant. Lower doses of radiation, particularly for children, are what many in the medical community are most concerned about, according to Dr Yanagisawa.
  • Humans are not yet capable of accurately measuring the low dose exposure or internal exposure," she explained, "Arguing 'it is safe because it is not yet scientifically proven [to be unsafe]' would be wrong. That fact is that we are not yet collecting enough information to prove the situations scientifically. If that is the case, we can never say it is safe just by increasing the annual 1mSv level twenty fold."
  • Her concern is that the new exposure standards by the Japanese government do not take into account differences between adults and children, since children's sensitivity to radiation exposure is several times higher than that of adults.
  • Al Jazeera contacted Prime Minister Naoto Kan's office for comment on the situation. Speaking on behalf of the Deputy Cabinet Secretary for Public Relations for the Prime Minister's office, Noriyuki Shikata said that the Japanese government "refers to the ICRP [International Commission on Radiological Protection] recommendation in 2007, which says the reference levels of radiological protection in emergency exposure situations is 20-100 mSv per year. The Government of Japan has set planned evacuation zones and specific spots recommended for evacuation where the radiation levels reach 20 mSv/year, in order to avoid excessive radiation exposure."
  • he prime minister's office explained that approximately 23bn yen ($300mn) is planned for decontamination efforts, and the government plans to have a decontamination policy "by around the end of August", with a secondary budget of about 97bn yen ($1.26bn) for health management and monitoring operations in the affected areas. When questioned about the issue of "acute radiation exposure", Shikata pointed to the Japanese government having received a report from TEPCO about six of their workers having been exposed to more than 250 mSv, but did not mention any reports of civilian exposures.
  • Prime Minister Kan's office told Al Jazeera that, for their ongoing response to the Fukushima crisis, "the government of Japan has conducted all the possible countermeasures such as introduction of automatic dose management by ID codes for all workers and 24 hour allocation of doctors. The government of Japan will continue to tackle the issue of further improving the health management including medium and long term measures". Shikata did not comment about Kodama's findings.
  • Nishio Masamichi, director of Japan's Hakkaido Cancer Centre and a radiation treatment specialist, published an article on July 27 titled: "The Problem of Radiation Exposure Countermeasures for the Fukushima Nuclear Accident: Concerns for the Present Situation". In the report, Masamichi said that such a dramatic increase in permitted radiation exposure was akin to "taking the lives of the people lightly". He believes that 20mSv is too high, especially for children who are far more susceptible to radiation.
  • Kodama is an expert in internal exposure to radiation, and is concerned that the government has not implemented a strong response geared towards measuring radioactivity in food. "Although three months have passed since the accident already, why have even such simple things have not been done yet?" he said. "I get very angry and fly into a rage."
  • Radiation has a high risk to embryos in pregnant women, juveniles, and highly proliferative cells of people of growing ages. Even for adults, highly proliferative cells, such as hairs, blood, and intestinal epithelium cells, are sensitive to radiation."
  • Early on in the disaster, Dr Makoto Kondo of the department of radiology of Keio University's School of Medicine warned of "a large difference in radiation effects on adults compared to children".Kondo explained the chances of children developing cancer from radiation exposure was many times higher than adults.
  • Children's bodies are underdeveloped and easily affected by radiation, which could cause cancer or slow body development. It can also affect their brain development," he said.Yanagisawa assumes that the Japanese government's evacuation standards, as well as their raising the permissible exposure limit to 20mSv "can cause hazards to children's health," and therefore "children are at a greater risk".
  • Kodama, who is also a doctor of internal medicine, has been working on decontamination of radioactive materials at radiation facilities in hospitals of the University of Tokyo for the past several decades. "We had rain in Tokyo on March 21 and radiation increased to .2 micosieverts/hour and, since then, the level has been continuously high," said Kodama, who added that his reporting of radiation findings to the government has not been met an adequate reaction. "At that time, the chief cabinet secretary, Mr Edano, told the Japanese people that there would be no immediate harm to their health."
  • n early July, officials with the Japanese Nuclear Safety Commission announced that approximately 45 per cent of children in the Fukushima region had experienced thyroid exposure to radiation, according to a survey carried out in late March. The commission has not carried out any surveys since then.
  • Now the Japanese government is underestimating the effects of low dosage and/or internal exposures and not raising the evacuation level even to the same level adopted in Chernobyl," Yanagisawa said. "People's lives are at stake, especially the lives of children, and it is obvious that the government is not placing top priority on the people's lives in their measures."Caldicott feels the lack of a stronger response to safeguard the health of people in areas where radiation is found is "reprehensible".
  • Millions of people need to be evacuated from those high radiation zones, especially the children."
  • Dr Yanagisawa is concerned about what she calls "late onset disorders" from radiation exposure resulting from the Fukushima disaster, as well as increasing cases of infertility and miscarriages."Incidence of cancer will undoubtedly increase," she said. "In the case of children, thyroid cancer and leukemia can start to appear after several years. In the case of adults, the incidence of various types of cancer will increase over the course of several decades."Yanagisawa said it is "without doubt" that cancer rates among the Fukushima nuclear workers will increase, as will cases of lethargy, atherosclerosis, and other chronic diseases among the general population in the effected areas.
  • Radioactive food and water
  • An August 1 press release from Japan's MHLW said no radioactive materials have been detected in the tap water of Fukushima prefecture, according to a survey conducted by the Japanese government's Nuclear Emergency Response Headquarters. The government defines no detection as "no results exceeding the 'Index values for infants (radioactive iodine)'," and says "in case the level of radioactive iodine in tap water exceeds 100 Bq/kg, to refrain from giving infants formula milk dissolved by tap water, having them intake tap water … "
  • Yet, on June 27, results were published from a study that found 15 residents of Fukushima prefecture had tested positive for radiation in their urine. Dr Nanao Kamada, professor emeritus of radiation biology at Hiroshima University, has been to Fukushima prefecture twice in order to take internal radiation exposure readings and facilitated the study.
  • The risk of internal radiation is more dangerous than external radiation," Dr Kamada told Al Jazeera. "And internal radiation exposure does exist for Fukushima residents."According to the MHLW, distribution of several food products in Fukushima Prefecture remain restricted. This includes raw milk, vegetables including spinach, kakina, and all other leafy vegetables, including cabbage, shiitake mushrooms, bamboo shoots, and beef.
  • he distribution of tealeaves remains restricted in several prefectures, including all of Ibaraki, and parts of Tochigi, Gunma, Chiba, Kanagawa Prefectures.Iwate prefecture suspended all beef exports because of caesium contamination on August 1, making it the fourth prefecture to do so.
  • yunichi Tokuyama, an expert with the Iwate Prefecture Agricultural and Fisheries Department, told Al Jazeera he did not know how to deal with the crisis. He was surprised because he did not expect radioactive hot spots in his prefecture, 300km from the Fukushima nuclear plant."The biggest cause of this contamination is the rice straw being fed to the cows, which was highly radioactive," Tokuyama told Al Jazeera.
  • Kamada feels the Japanese government is acting too slowly in response to the Fukushima disaster, and that the government needs to check radiation exposure levels "in each town and village" in Fukushima prefecture."They have to make a general map of radiation doses," he said. "Then they have to be concerned about human health levels, and radiation exposures to humans. They have to make the exposure dose map of Fukushima prefecture. Fukushima is not enough. Probably there are hot spots outside of Fukushima. So they also need to check ground exposure levels."
  • Radiation that continues to be released has global consequences.More than 11,000 tonnes of radioactive water has been released into the ocean from the stricken plant.
  • Those radioactive elements bio-concentrate in the algae, then the crustaceans eat that, which are eaten by small then big fish," Caldicott said. "That's why big fish have high concentrations of radioactivity and humans are at the top of the food chain, so we get the most radiation, ultimately."

The Thorium Reactor, A Nuclear Energy Alternative [19Sep11] - 0 views

  • After Fukushima a great deal of awareness on the dangers of nuclear energy has ignited a series of reactions in society, mainly a generalized rejection to nuclear energy and a call to develop cleaner and safer sources of energy. When thinking about nuclear energy mainly 2 sources come to peoples minds, solar and wind power condemning any sort of nuclear power.  Nuclear power has been associated with Weapons of Mass Destruction, radiation sickness and disease.  However, this is not due to the nuclear power itself but due to the nuclear fuel used to generate this nuclear power.
  • The above are just some of the most common byproducts, (better known as nuclear waste) of a nuclear fuel cycle, all of these substances are extremely poisonous, causing a variety of diseases, cancers and genetic mutations to the victim.  The worst part is that most of them remain in the environment of decades or even thousands of years, so if accidentally released to the environment they become a problem that future generations have to deal with.  Therefore, in nuclear energy the problem is in the fuel not in the engine. Lets start with the Thorium Reactors.  Thorium is a naturally occurring radioactive chemical element, found in abundance throughout the world.  It is estimated that every cubic meter of earth’s crust contains about 12 grams of this mineral, enough quantity to power 1 person’s electricity consumption for 12-25 years.  Energy is produced from thorium in a process known as the Thorium Fuel Cycle, were a nuclear fuel cycle is derived from the natural abundant isotope of thorium.
  • In today’s world the main fuel for nuclear power is a naturally occurring radioactive mineral, Uranium.  This mineral is one of the most dense metals in the periodic table which allows it to reach a chain reaction that can yield huge amounts of energy that can be exploited for an extended period of time.  Unfortunately the nuclear fuel cycle of Uranium produced extremely dangerous byproducts, commonly known as nuclear waste.  These are produced in liquid, solid and gaseous form in a wide variety of deadly substances, such as: Iodine 131 Strontium 90 Cesium 137 Euricium 155 Krypton 85 Cadmium 113 Tin 121 Samarium 151 Technetium-99

  • Thorium can be used as fuel in a nuclear reactor, and it is a fertile material, which allows it to be used to produce nuclear fuel in a breeder reactor.  These are some of the benefits of Thorium reactors compared to Uranium. Weapons-grade fissionable material is harder to retrieve safely and clandestinely from a thorium reactor; Thorium produces 10 to 10,000 times less long-lived radioactive waste; Thorium comes out of the ground as a 100% pure, usable isotope, which does not require enrichment, whereas natural uranium contains only 0.7% fissionable U-235; Thorium cannot sustain a nuclear chain reaction without priming,[22] so fission stops by default. The following conference by Kirk Sorensen explains a Liquid-Fuoride Thorium Reactor a next generation nuclear reactor.

Fukushima desolation worst since Hiroshima, Nagasaki [07Oct11] - 0 views

  • Beyond the police roadblocks that mark the no-go zone around the wrecked Fukushima No. 1 nuclear plant, 2-meter-tall weeds invade rice paddies and vines gone wild strangle road signs along empty streets. Takako Harada, 80, returned to an evacuated area of Iitate, a village in Fukushima Prefecture, to retrieve her car. Beside her house is an empty cattle pen, the 100 cows slaughtered on government orders after radiation from the March 11 atomic disaster saturated the area, forcing 160,000 people to move away and leaving some places uninhabitable for two decades or more. "Older folks want to return, but the young worry about radiation," said Harada, whose family ran the farm for 40 years. "I want to farm, but will we be able to sell anything?"
  • What is emerging six months since the nuclear meltdowns at the Tokyo Electric Power Co. plant is a radioactive zone bigger than that left by the 1945 atomic bombings at Hiroshima and Nagasaki.
  • While nature reclaims the 20-km no-go zone, Fukushima's ¥240 billion a year farm industry is being devastated and tourists that hiked the prefecture's mountains and surfed off its beaches have all but vanished.

  • A government panel investigating Tepco's finances estimated the cost of compensation to people affected by the nuclear disaster will exceed ¥4 trillion.
  • The bulk of radioactive contamination cuts a 5- to 10-km-wide swath of land running as far as 30 km northwest of the nuclear plant, surveys of radiation hot spots by the science ministry show. The government extended evacuations beyond the 20-km zone in April to cover this corridor, which includes parts of Iitate.
  • Some people believed A-bomb survivors could emit radiation and others feared radiation caused genetic mutations, said Evan Douple, associate chief of research at the Radiation Effects Research Foundation in Hiroshima. An examination of more than 77,000 first-generation children in Hiroshima and Nagasaki after the bombings found no evidence of mutations, he said.
  • On April 26, 1986, an explosion at the Chernobyl reactor hurled 180 metric tons of nuclear fuel into the atmosphere, creating the world's first exclusion zone of 30 km around a nuclear plant. A quarter of a century later, the zone is still classed as uninhabitable. About 300 residents have returned despite government restrictions.
  • Tepco's decision in the 1960s to name its atomic plant Fukushima No. 1 has today associated a prefecture of about 2 million people that's almost half the size of Belgium with radiation contamination. In contrast, Chernobyl is the name of a small town near the namesake plant in what today is Ukraine.
  • No formal evacuation zone was set up in Hiroshima after the U.S. dropped an atomic bomb on the city on Aug. 6, 1945, though as the city rebuilt relatively few people lived within 1 km of the hypocenter, according to the Hiroshima Atomic Bomb Museum. Food shortages forced a partial evacuation of the city in summer 1946.
  • While radiation readings are lower in Fukushima than Hiroshima, Abel Gonzales, the vice chairman of the International Commission on Radiological Protection, said similar prejudices may emerge. "Stigma. I have the feeling that in Fukushima this will be a very big problem," Gonzales said during a symposium held in the city of Fukushima on the six-month anniversary of the disaster. Some children who fled Fukushima are finding out what Gonzales means. Fukushima schoolchildren were being bullied at their new school in Chiba Prefecture for "carrying radiation," the Sankei Shimbun reported in April, citing complaints made to education authorities. An 11-year-old Fukushima boy was hospitalized in Niigata Prefecture after being bullied at his new school, Kyodo News reported April 23.
  • Radiation risks in the 20-km zone forced the evacuation of about 8 percent, or 160,000, of some 2 million people who live in Fukushima. Almost 56,000 were sent to areas outside Fukushima, prefecture spokesman Masato Abe said. More than 8,000 left on their own accord because of radiation fears, Abe said
  • side the evacuation areas, levels of radiation higher than the government's criteria for evacuation have been recorded at 89 of 210 monitoring posts. At 24 of the sites, the reading was higher than the level at which the International Atomic Energy Agency says increases the risk of cancer. Japan Atomic Energy Institute researcher Toshimitsu Homma used science ministry data to compare the geographic scale of the contamination in Fukushima with Chernobyl.
  • He estimates the no-go zone in Fukushima will cover 132 sq. km, surrounded by a permanent monitoring area of 264 sq. km, assuming Japan follows the criteria set by the Soviet Union in 1986. The two areas combined equal about half the size of the five boroughs that comprise New York City. In the case of Chernobyl, the two zones cover a land mass 25 times greater, according to Homma's figures.
  • "Contradiction in some official statements, and the appearance of nonscientifically based 'expert' voices, confused and added stress to the local populations in each case," said Evelyn Bromet, a distinguished professor in the department of psychiatry at State University of New York, Stony Brook. "Lies got told, contradictions got told. In the end it's easier to believe nobody," Bromet said in an interview, citing mental health studies she did on people in the areas.
  • What radiation hasn't ruined, the earthquake and tsunami devastated. Fukushima Prefecture welcomed 56 million domestic and overseas visitors in 2009, equal to 44 percent of Japan's population.
  • The coastal town of Minamisoma this year canceled its annual qualifying stage for the world surfing championship, part of a waterfront that lured 84,000 beachgoers in July and August last year, said Hiroshi Tadano, head of the town's economic division. This year, nobody visited the beaches in the two months. "Most of the beaches are destroyed," Tadano said. "And of course, radiation played its part."
  • The area's biggest festival, Soma Nomaoi, a re-enactment of samurai battles, attracted 200,000 visitors last year. This year 37,000 came. Of the 300 horses typically used in the event, 100 were drowned in the tsunami and another 100 were evacuated due to radiation, Tajino said. Minamisoma resident Miyaguchi, 54, lost his home and parents in the tsunami. He quit his job at Tepco, leaving him unemployed and housed in an evacuation center

Animals suffer the effects of Fukushima nuclear devastation [07Jul11] - 0 views

  • The Fukushima nuclear accident in Japan has taken a massive toll on animals. The fate of wildlife is largely unknown, but domestic pets and livestock continue to suffer.   Livestock were forcibly abandoned and left behind to starve. Cows contaminated with cesium five times the permissible level have been slaughtered. Buried in the ground, their radioactive carcasses will continue to contaminate the land for decades if Chernobyl is any indication.   Family pets were left behind, tied, abandoned in homes, or left to roam the streets in search of food. Their owners were forbidden to return or were allowed to make brief visits to feed them, often too late. A rabbit born without ears is stoking fears of birth defects and genetic damage among humans while whales have been caught that are found to be contaminated with radioactive cesium. In the event of US reactor accidents, citizens are encouraged to evacuate with their pets. However, evacuation shelters and most hotels do not allow animals. Livestock, of course, cannot be evacuated.

Earless baby bunny near Fukushima Daiichi stokes fears of radiogenic mutation... - 0 views

  • A baby bunny apparently born without ears (photo at left) in the town of Namie, near the massively leaking Fukushima Daiichi nuclear power plant, has raised concerns about mutagenic effects caused by radioactivity in the environment. Naysayers abound, despite evidence of genetic mutations in animals (such as a two headed calf) and plants (including deformed flowers) in the aftermath of the Three Mile Island meltdown collected and documented by Mary Osborn; numerous scientific studies showing adverse impacts on wildlife populations in Chernobyl contaminated regions, such as on birds by Dr. Tim Mousseau of the University of South Carolina; and, further back in time, an epidemic of ewe deaths in southwest Utah immediately downwind of the Nevada Nuclear Weapons Test Site. An excellent book by John G. Fuller, "The Day We Bombed Utah," published in 1984, recounts how Mormon sheep farmers experienced unprecedented sheep and ewe deaths in the early 1950s, shortly after nuclear weapons blasts upwind in Nevada. The farmers sued the Atomic Energy Commission for damages. AEC research scientists swore, under oath, that they had no evidence that radioactivity could cause such a die off in sheep and ewes. However, over a quarter century later, it was shown by the sheep farmers and their attorney that the AEC had lied -- they had conducted experiments on sheep at the Hanford Nuclear Reservation in Washington State: they observed die offs very similar to what occurred in Utah. The same judge who had presided over the original trial heard the new evidence as well, and ruled that the AEC had perpetrated a fraud upon the court. Fuller also wrote "We Almost Lost Detroit," published in 1975, about the 1966 partial meltdown at the Fermi 1 experimental plutonium breeder reactor in Monroe, Michigan.

Citizens' forum queries nuclear 'experts' [23Oct11] - 0 views

  • To whom does scientific debate belong? That was a central question raised by many of the 200-plus people who attended a citizens' forum in Tokyo on Oct. 12, as they criticized the ways in which the Japanese government and radiation specialists working for it are assessing and monitoring the health effects of the ongoing nuclear disaster at the Fukushima No. 1 nuclear power plant. The daylong conference, organized by the Japanese citizens' groups SAY-Peace Project and Citizens' Radioactivity Measuring Station (CRMS), featured experts who dispute much of the evidence on which the government has based its health and welfare decisions affecting residents of Fukushima Prefecture and beyond. Organizers of the event were also demanding that the government take into consideration the views of non-experts — and also experts with differing views from those of official bodies such as the International Commission on Radiological Protection (ICRP). The Japanese government has constantly referred to the ICRP's recommendations in setting radiation exposure limits for Fukushima residents.
  • One of the driving forces for the citizens' forum was a desire to challenge the conduct and much of the content of a conference held Sept. 11-12 in Fukushima, titled the "International Expert Symposium in Fukushima — Radiation and Health Risk." That conference, sponsored by the Nippon Foundation, involved some 30 scientists from major institutions, including the ICRP, the World Health Organization, the International Atomic Energy Agency and the United Nations Scientific Committee on the Effects of Atomic Radiation. Although the proceedings were broadcast live on U-stream, the event itself was — unlike the Tokyo forum — closed to the public. Some citizens and citizens' groups claimed that this exclusion of many interested and involved parties — and the event's avowed aim of disseminating to the public "authoritative" information on the health effects of radiation exposure — ran counter to the pursuit of facilitating open and free exchanges among and between experts and citizens on the many contentious issues facing the nation and its people at this critical time.
  • In particular, there was widespread criticism after the Fukushima conference — which was organized by Shunichi Yamashita, the vice president of Fukushima Medical University and a "radiological health safety risk management advisor" for Fukushima prefectural government — that its participants assumed from the outset that radioactive contamination from the plant's wrecked nuclear reactors is minimal. Critics also claimed that the experts invited to the conference had turned a collective blind eye to research findings compiled by independent scientists in Europe in the aftermath of the 1986 Chernobyl nuclear disaster in present-day Ukraine — specifically to findings that point to various damaging health consequences of long-term exposure to low-level radiation. So it was that those two citizens' groups, angered by these and other official responses to the calamity, organized the Oct. 12 conference held at the National Olympics Memorial Youth Center in Shibuya Ward. Among the non-experts and experts invited to attend and exchange their views were people from a wide range of disciplines, including sociology, constitutional law and pediatrics. On the day, some of the speakers took issue with the stance of the majority of official bodies that the health damage from Chernobyl was observed only in a rise in the number of cases of thyroid cancers.

  • Eisuke Matsui, a lung cancer specialist who is a former associate professor at Gifu University's School of Medicine, argued in his papers submitted to the conference that the victims of Chernobyl in the neighboring present-day country of Belarus have suffered from a raft of other problems, including congenital malformations, type-1 diabetes and cataracts. Matsui cited a lengthy and detailed report of research by the Russian scientists Alexey V. Yablokov, Vassily B. Nesterenko and Alexey V. Nesterenko that was published in 2007, and republished in English in 2009 by the New York Academy of Sciences under the title "Chernobyl: Consequences of the Catastrophe for People and the Environment." Matsui stressed that, based on such evidence, the Japanese government should approve group evacuations of children — at the expense of the plant's operator, Tokyo Electric Power Co. — from certain parts of Fukushima Prefecture. He cited some areas of the city of Koriyama, 50 to 60 km from the stricken nuclear plant, where soil contamination by radioactive cesium-137 has reached 5.13 Curies per sq. km. That is the same as in areas of Ukraine where residents were given rights to evacuate, Matsui said. In fact in June, the parents of 14 schoolchildren in Koriyama filed a request for a temporary injunction with the Fukushima District Court, asking it to order the city to send their children to schools in safer areas.
  • In the ongoing civil suit, those parents claim that the children's external radiation exposure has already exceeded 1 millisievert according to official data — the upper yearly limit from all sources recommended by the ICRP for members of the public under normal conditions. Following a nuclear incident, however, the ICRP recommends local authorities to set the yearly radiation exposure limit for residents in contaminated areas at between 1 and 20 millisieverts, with the long-term goal of reducing the limit to 1 millisievert per year. Meanwhile, Hisako Sakiyama, former head researcher at the National Institute of Radiological Sciences, delved into the non-cancer risks of exposure to radiation. In her presentation, she referred to a report compiled in April by the German Affiliate of International Physicians for the Prevention of Nuclear War (IPPNW). Titled "Health Effects of Chernobyl: 25 years after the reactor catastrophe," this documents an alarmingly high incidence of genetic and teratogenic (fetal malformation) damage observed in many European countries since Chernobyl.
  • Sakiyama also pointed out that the German report showed that the incidence of thyroid cancer due to radiation exposure was not limited to children. For instance, she cited IPPNW survey findings from the Gomel district in Belarus, a highly-contaminated area, when researchers compared the incidence of thyroid cancer in the 13 years before the Chernobyl explosion and the 13 years after. These findings show that the figures for the latter period were 58 times higher for residents aged 0-18, 5.3 times higher for those aged 19-34, 6 times higher for those aged 35-49, and 5 times higher for those aged 50-64. "In Japan, the government has a policy of not giving out emergency iodine pills to those aged 45 and older (because it considers that the risk of them getting cancer is very low),"' Sakiyama said. "But the (IPPNW) data show that, while less sensitive compared to children, adults' risks go up in correspondence with their exposure to radioactivity."
  • Further post-Chernobyl data was presented to the conference by Sebastian Pflugbeil, a physicist who is president of the German Society for Radiation Protection. Reporting the results of his independent research into child cancers following the Chernobyl disaster, he said that "in West Germany ... with an exposure of 1 millisievert per year, hundreds of thousands of children were affected." He noted, though, that any official admissions regarding health damage caused by the 1986 disaster in the then Soviet Union came very slowly and insufficiently in Europe. Indeed, he said the authorities denied there were health risks for years afterward. In response, an audience member who said he was a science teacher at a junior high school in Kawaguchi, Saitama Prefecture, asked Pflugbeil to exactly identify the level of exposure beyond which residents should be evacuated. While acknowledging that was a very difficult question, the German specialist noted later, however, that he would think pregnant women should probably leave Fukushima — adding, "I have seen many cases over the years, but I come from Germany and it's not easy to judge (about the situation in Japan)."
  • At a round table discussion later in the day, as well as discussing specific issues many participants made the point that science belongs to the people, not just experts — the very point that underpinned the entire event. As Wataru Iwata, director of the Fukushima-based citizens' group CRMS, one of the forum's organizers (which also conducts independent testing of food from in and around Fukushima Prefecture) put it: "Science is a methodology and not an end itself." In the end, though the citizens' forum — which ran from 9:30 a.m. to 10 p.m. — arrived at no clear-cut conclusions, organizers said that that in itself was a good outcome. And another conference involving citizens and scientists is now being planned for March 2012.

Soviet Radiation Doctor: We were wrong - A huge new group has appeared… The c... - 0 views

  • Title: True Stories: After The Apocalypse (Nuclear Testing Effects) Uploader: AfterApocalypseMovie Upload Date: April 27, 2011 Description: During the Soviet era, the people of Semipalatinsk in Kazakhstan were used as human guinea pigs in the testing of nuclear weapons. Today they live with the consequences. Whilst sheep graze in radioactive bomb craters, many in the population believe that the testing is the reason why one in twenty children are born with birth defects. [...] Transcript Excerpts (Emphasis Added)
  • At 20:35 -- 21:00 in Dr. Boris Gusev, Semipalatinsk Institute of Radiation Medicine: “We knew precisely where the radiation was.” “We knew precisely how much of the different types of radiation that people were being exposed to.” “What dose the population was receiving.” “We knew everything.” At 46:30 -- 47:10 in Dr. Boris Gusev, Semipalatinsk Institute of Radiation Medicine:
  • “Over the last 15 years we have thoroughly analyzed all the material in these archives.” “We have made our conclusions and published our research, and at the same time we have continued our planned research of the population.” “Now a huge new group has appeared of 250,000-270,000 people.” “These are the children of parents who have been irradiated.” “We thought that everything would go smoothly, that chromosonal damage and genetic effects would be confined to the generation of people who were irradiated and they could not be inherited by future generations.” “But it turned out that this was wrong.”
