DOE Releases Draft EIS on Proposed Low-Level Nuclear Waste Sites, Disposal Methods [21F... - 0 views

  • The Department of Energy on Friday issued a draft environmental impact statement (EIS) on low-level radioactive waste disposal, with public meetings set for April and May in cities near potential waste sites in Oregon, Idaho, Washington, Nevada, New Mexico and South Carolina. The EIS addresses greater-than-class-C (GTCC) low-level-radioactive waste (LLRW) as DOE considers new and existing storage facilities. GTCC waste comes from power plants, medical treatments, medical diagnostics and oil and gas exploration, as well as other industrial processes. The EIS and waste sites do not involve high-level waste like spent fuel.
  • In a release, DOE estimates current GTCC and GTCC-like LLRW in storage at 1,100 cubic meters. The EIS estimates an additional 175 cubic meters of waste will be generated each year over the next six decades. In looking for places to store that waste, the EIS analyzes the potential environmental impacts of using both new and existing waste facilities. Disposal methods evaluated include deep geological repository, intermediate depth boreholes, enhanced near-surface trenches and above-grade vaults
  • “disposal locations analyzed include the Hanford Site in Washington; Idaho National Laboratory in Idaho; the Los Alamos National Laboratory, the Waste Isolation Pilot Project (WIPP) and the WIPP vicinity in New Mexico; the Nevada National Security Site (formerly the Nevada Test Site) in Nevada; and the Savannah River Site in South Carolina. The Draft EIS also evaluates generic commercial disposal sites in four regions of the U.S., as well as a no action alternative.”

  • DOE has not yet identified a preferred alternative for waste disposal, but a preferred alternative or combination of alternatives will be identified in the final EIS. Before making a final decision on disposal method or location, the agency would need to submit its findings to Congress and wait for legislative action.

Radiation from Fukushima may lead to decreased population in Japan [11Aug11] - 0 views

  • In the post-disaster environment, there is now another disincentive to have children: concerns about radiation. Though long-term health implications of exposure to low doses of radiation is disputed, medical officials deem infants to be more prone to the dangers than adults. “Before the disaster, I wanted to have another child, but now I don’t think I can. I used to work at the Fukushima Daini Nuclear Plant,” says Yuki Sato, referring to the facility a few miles from the stricken Daiichi facility. Ms. Sato and her 6-year-old son are now living at an evacuation center in Koriyama City on the western edge of Fukushima Prefecture. She is concerned about radiation she may have been exposed to following the accident. “I asked the medical staff at the center whether a baby would be affected,” says Sato. “They said it ‘should' be OK.' What kind of answer is that when talking about having a baby?” Although few people were working as close to the Fukushima accident as Sato, women across the northeast of Japan, and as far away as Tokyo, are concerned about having children amid ongoing fears of the effects of radiation.

South Africa: The Return of Highly Enriched Uranium to the U.S. in Context [17Aug11] - 0 views

  • On 17 August 2011, the National Nuclear Security Administration (NNSA) of the United States issued a press release announcing that the South African government, through the Nuclear Energy Corporation (Necsa), had returned 6,3kg of highly enriched uranium (HEU) spent fuel to the US for safe storage and ultimately for destruction.
  • NNSA is a semi-autonomous agency within the US Department of Energy (DOE) responsible among other things for maintaining and enhancing the safety, security, reliability and performance of the US nuclear weapons stockpile. The shipment arrived at Savannah River Site (SRS) on 16 August. The SRS is a key DOE industrial complex dedicated to nuclear weapons stockpile stewardship and nuclear materials destruction in support of the US nuclear non-proliferation efforts. It is situated 20 miles south of Aiken, South Carolina.
  • Subsequent press reports and releases by mainly US-based academics and NGOs lauded this development as a significant step in 'reducing and securing vulnerable [emphasis added] radioactive materials held at civilian sites around the world' and stated that it represents an important effort to 'strengthen the world's defences against nuclear terrorism'. While at first reading these may seem reasonable assertions, a number of important caveats need to be highlighted.
  • ...5 more annotations...
  • Firstly, 'spent fuel' is defined as fuel whose elements have been removed from the reactor because the fissionable material they contain has been depleted to a level near where it can no longer sustain a chain reaction. The high concentration of radioactive fission products in spent power-reactor fuel creates a gamma-radiation field, which at a distance of a metre would be lethal. South Africa, or more accurately Necsa, no longer has any use for this material.
  • Secondly, the US and South Africa have been working constructively for a number of years on various peaceful use applications of nuclear material and in particular on the need to minimise the use of HEU. Examples of such co-operation are the conversion of South Africa's SAFARI-1 reactor to low enriched uranium (LEU) fuel as well as training in medical responses to nuclear and radiological emergencies. Indeed, today South Africa is leading the transition to produce the medical isotope molybdenum-99 (Mo-99) with LEU rather than HEU.
  • Zuma was one of only five African Heads of State or government invited to develop concrete measures towards ensuring that nuclear materials under their control are not stolen or diverted (the others being Algeria, Egypt, Morocco and Nigeria). They pledged to improve security as changing conditions may require, and to exchange best practices and practical solutions for doing so. The Summit's final communiqué also highlighted the fact that 'highly enriched uranium and separated plutonium require special precautions'.
  • Thirdly, the return is not unique. The repatriation of used and unused HEU fuel to its country of origin - either the US or Russia - has been an international goal since the early 1980s. Some 1,249kg of US-origin highly enriched uranium from sites around the world have already been returned, including from Chile in April 2010 just after the earthquake the previous February.
  • Finally, and perhaps most importantly, the spent fuel storage facility at Necsa is not, and has never been, 'vulnerable' - in the sense of being in danger of being accessed by organisations or persons with criminal intent or worse, with terrorist ideologies.

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.
  • 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."
  • 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.
  • 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."
  • 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.
  • 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."
  • 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".
  • 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.
  • 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."

Atomic workers ridiculed in training manual [28Sep11] - 0 views

  • Advocates for atomic workers sickened by on-the-job radiation exposure at places like the Miamisburg Mound Plant say they’re outraged by a training manual for a federal compensation program that refers to a hypothetical claimant as “Freddy Krueger,” the name of a horror movie character whose face was badly burned.The undated Labor Department manual, used in training people who screen applicants for possible compensation and medical benefits, also refers to the pathologist in a hypothetical dead worker’s case as the fictitious serial killer Dr. Hannibal Lecter.
  • The manual’s jocular attitude toward workers who have suffered from cancers and other serious illnesses is “indicative of the disrespect that’s shown to claimants” by Labor Department officials, said worker advocate Deb Jerison of Yellow Springs, who heads a nonprofit that helps sick atomic workers and their survivors obtain federal benefits. Some of the workers have died from their illnesses.Labor officials did not return repeated phone calls seeking comment.
  • The Energy Employees Occupational Illness Compensation Program, administered by the Labor Department, provides medical benefits and compensation for sick atomic workers, if it is shown their illnesses were caused by occupational exposures. Workers suffering from cancers and some other illnesses known to be caused by radiation exposures can receive lump-sum payments, as can certain survivors.For decades, the Energy Department claimed that none of its workers was sickened by radioactive exposures. Since the program was established in 2001, it has paid $7.4 billion in compensation and doctor bills for more than 86,000 claimants.Jerison obtained the manual in a Freedom of Information Act request to Labor and found it riddled with pop-culture references.

  • “None of the (hypothetical) claims examiners had names like this. It was like ‘Jane Doe.’ Bland names, which is appropriate (for the tone of a training manual),” said Jerison, whose father, Mound physicist James Goode, died in 1960 at age 36. After a six-year process, Jerison helped her mother win survivor benefits, but her mother died in 2008 before the money arrived.In a letter to Labor officials, chemist David Manuta of Waverly, a member of the Alliance of Nuclear Worker Advocacy Groups, called the humor “examples of (a) history of disrespect” for applicants.Manuta also criticized the “shameful comments” in May of program Director Rachel Leiton, who, according to a meeting transcript, told an advisory board that sick workers couldn’t be trusted to tell the truth in affidavits about their work history at atomic plants. Many cases involve decades-ago employment for which records are hard to find.

How late are we? | Fukushima Diary [28Sep11] - 0 views

  • Unusual form of plants are being found every where in Japan. Today,a Japanese traditional root vegetable “Myoga” was found ,which was four times bigger than usual size. The farmer said ,he has never seen such big Myoga. He has been farming there since his grand parents’ generation. http://www.yomiuri.co.jp/national/news/20110928-OYT1T00324.htm Should we stay here ? The answer is no. and the right question is When should we have evacuated ? Today’s news.
  • From a survey conducted by the local hospital association, it became clear that 12% of the full time medical doctors who worked at the hospitals in Fukushima Prefecture have retired voluntarily. That means 125 doctors less in Fukushima Prefecture’s hospitals. The number of nurses who retired also rose, 407 of them - which means 5% (form 42 hospitals) - it is believed to have retired because they had to evacuate. As a consequence, a part of the clinical departments and the night emergency medical service in the prefecture’s hospitals are inactive. The survey was made by the end of July to check the conditions in which the doctors work in the prefecture. It was conducted in 127 hospitals - from the total of 139 hospitals -,which are members of the same association. The survey was answered by only 54 hospitals.
  • Mr.Koide was stopped to publish a data on 3/18. It is the data to show how much radiation flew to Tokyo. The data was taken in Tokyo ,on 3/15. It reads, I-131 720Bq/m3 I-132 450 Bq/m3 I-133 20 Bq/m3 Te-132 570 Bq/m3 Cs-134 110 Bq/m3 Cs-136 21 Bq/m3 Cs-137 130 Bq/m3 Effective dose = 210uSv/d The safety limit of effective dose per day is 55 uSv. It was about four times as the safety limit.

  • As for the nurses, their number decreased by 16%: (44 nurses, including two from one hospital located in the danger zone) in Minamisoma city, by 8% (113) in 7 hospitals in Iwaki city, in 9 hospitals from Fukushima cityi and 6 hospitals of Kooriyama-shi by 4% , which means 68 and 54 nurses respectivly.
  • http://www.yomiuri.co.jp/national/news/20110928-OYT1T00658.htm?from=tw
  • At least 12% of the doctors “quit” and left Fukushima by the end of July. It’s very rare for a doctor to “quit” in Japan. They “knew” the accurate health risk because of radiation. Another news of today.
  • The main municipalities in which a high percentage of doctors’ retiring was recorded even before the nuclear accident were: Minamisoma-shi 46% (13 doctors, including one doctor from o hospital located in a danger zone ), Iwaki-shi 5 hospitals, 23% of the doctors (31doctors ), Fukushima city 6 hospitals 9% (41 ) doctors , Kooriyama-shi 4 hospitals 8% (25 ) doctors.
  • We should have evacuated from Tokyo before 3/15. Here are the tweets of an actual worker of Fukushima,
  • Happy20790
  • We done measuring hydrogen amount in reactor 1. It seems to be an abnormal test, specialists came to the plant. The result was 60% = hydrogen. The rest is full of other kinds of flammable gas.
  • It may explode only if it touches air. It can’t be released or replaced by nitrogen, so we can only inject nitrogen from isolation valves. hope it doesn’t let air come into the pipe..
  • Since 311,we have done variety of the works but this is the most tricky mission.

Breaking News: Recriticality may be happening continuously [01Oct11] - 0 views

  • In addition to two previous posts on this issue:”Fukushima went back to recriticality almost for 100%” and “Fukushima in recriticality” it turns out that they also detected I-131 in North and Western Japan. 1) in Miyagi. 42 Bq/kg – 8/9/2011 41 Bq/kg – 9/6/2011 2) In Nagasaki 563 Bq/kg – 8/4/2011 151 Bq/kg – 8/11/2011 44 Bq/kg – 8/22/2011
  • When it comes to the detection of I-131, some people always try to deny the possibility of recriticality to reassure themselves by bringing up the possibility of medical usage of Iodine. However, in a previous post, Breaking News: Fukushima went back to recriticality almost for 100%, the possibility of the medical usage of Iodine was completely denied by asking the local hospitals. From all the data,it is possible to think Fukushima still goes into the state of recriticality on and off http://onodekita.sblo.jp/article/48003171.html Kuri Sewage Odei 20110906

Clinton Nuclear Plant moving into molybdenum production [14Sep11] - 0 views

  • The Clinton nuclear power plant in Illinois could be set to make a vital isotope for nuclear medicine after GE-Hitachi Nuclear Energy and Exelon announced a feasibility study into the production of molybdenum-99 at the plant.
  • Molybdenum-99 (Mo-99) decays to produce technetium-99m (Tc-99m) that is used in around 50 million medical diagnostic imaging procedures every year. With a half-life of only six hours, Tc-99m is too short-lived to be transported to hospitals so is produced where it is needed in generators containing Mo-99. As Mo-99 itself has a half-life of only 66 hours, the world needs reliable, steady supplies of the isotope, most of which is made by irradiating uranium-235 targets inside a research reactor.
  • Most of the world's Mo-99 comes from only five research reactors: Canada's NRU, the Netherlands' HFR, Belgium's BR-2, France's Osiris and South Africa's Safari-1. Issues at some of the reactors in recent years have led to worldwide problems with the supply of this vital isotope. Earlier this year, a high-level committee of the OECD Nuclear Energy Agency called on governments to address underlying economic structures to help to ensure reliable supplies.

  • Clinton is a General Electric-designed 1067 MWe boiling water reactor (BWR) operated by Exelon in Illinois. It already produces cobalt-60 (Co-60) for medical use by inserting non-radioactive target rods of cobalt-59 into the reactor where they capture free neutrons and are transformed into Co-60. Now GE-Hitachi has said it is working alongside the US National Nuclear Security Administration's (NNSA) Global Threat Reduction Initiative to develop a design to allow the insertion and removal of activated molybdenum. This would be done on a weekly basis.

PhysOrg Mobile: Ukraine begins construction of new nuclear waste storage [05Oct11] - 0 views

  • Ukraine launched construction of a new facility Wednesday to stockpile industrial nuclear waste in the contaminated zone around its Chernobyl plant, site of the worst nuclear accident of the last 25 years. The facility will be launched in early 2013 and will only house Ukrainian nuclear waste, a large part of which is currently stored in "poorly equipped" locations, Chernobyl plant's spokeswoman Maya Rudenko said. "It will not be for material from nuclear plants" but waste from medical facilities and industries, she told AFP. The facility will have capacity for 400,000 capsules with such waste and have a lifespan of 50 years.
  • Construction of the storage facility is estimated to cost over 11 million euros ($14.6 million) to come from Britain, which will provide eight million British pounds ($12 million) and the European Commission (two million euros, or $2.6 million). The Chernobyl nuclear plant is located about 100 kilometres (60 miles) north of Kiev and close to the borders with Russia and Belarus. Its fourth reactor exploded in April 1986 with fallout hitting the three Soviet republics along with a large part of Europe.

Lifetime Cumulative Limit of Internal Radiation from Food to Be 100 Millisieverts in Ja... - 0 views

  • External radiation is not counted in this number, as opposed to their draft plan in July which did include external radiation, and it is in addition to the natural radiation exposure (by which is meant pre-Fukushima natural).The experts on the Commission didn't rule on the radiation limit for children, leaving the decision to the Ministry of Health and Labor as if the top-school career bureaucrats in the Ministry would know better.Yomiuri and other MSMs are spinning it as "tightening" the existing provisional safety limits on food.From Yomiuri Shinbun (10/27/2011):
  • The Food Safety Commission under the Cabinet Office has been deliberating on the health effect of internal radiation exposure from the radioactive materials in food. On October 27, it submitted its recommendation to set the upper limit on lifetime cumulative radiation from food at 100 millisieverts.
  • On receiving the recommendation, the Ministry of Health and Labor will start setting the detailed guidelines for each food items. They are expected to be stricter than the provisional safety limits set right after the Fukushima I Nuclear Plant accident. The Radiation Commission under the Ministry of Education will review the guidelines to be set by the Ministry of Health and Labor, and the new safety limits will be formally decided.

  • According to the draft of the recommendation in July, the Food Safety Commission was aiming at setting "100 millisieverts lifetime limit" that would include the external radiation exposure from the nuclides in the air. However, based on the opinions from the general public, the Commission decided that the effect of external radiation exposure was small and focused only on internal radiation exposure from food.
  • If we suppose one's lifetime is 100 years, then 1 millisievert per year would be the maximum. The current provisional safety limit assumes the upper limit of 5 millisievert per year with radioactive cesium alone. So the new regulations will inevitably be stricter than the current provisional safety limits.
  • In addition, the Commission pointed out that children "are more susceptible to the effect of radiation", but it didn't cite any specific number for children. The Commission explained that it would be up to the Ministry of Health and Labor and other agencies to discuss" whether the effect on children should be reflected in the new safety limits.Oh boy. So many holes in the article.First, I suspect it is a rude awakening for many Japanese to know that the current provisional safety limits for radioactive materials in food presuppose very high internal radiation level already. The Yomiuri article correctly says 5 millisieverts per year from radioactive cesium alone. The provisional safety limit for radioactive iodine, though now it's almost irrelevant, is 2,000 becquerels/kg, and that presupposes 2 millisieverts per year internal radiation. From cesium and iodine alone, the provisional safety limits on food assume 7 millisievert per year internal radiation.
  • (The reason why the radioactive iodine limit is set lower than that for radioactive cesium is because radioactive iodine all goes to thyroid gland and gets accumulated in the organ.)I am surprised that Yomiuri even mentioned the 5 millisieverts per year limit from cesium exposure alone. I suspect it is the first time ever for the paper.Second, the article says the Commission decided to exclude external radiation from the "100 millisieverts" number because of the public opinion. Which "public" opinion are they talking about? Mothers and fathers with children? I doubt it. If anything, the general public (at least those who doesn't believe radiation is good for them) would want to include external radiation so that the overall radiation limit is set, rather than just for food.
  • Third, and most importantly, if the proposed lifetime limit of 100 millisieverts is only for internal radiation from FOOD, then the overall internal radiation could be much higher. Why? Because, pre-Fukushima, the natural internal radiation from food in Japan was only 0.41 millisievert per year (mostly from K-40), or 28% of total natural radiation exposure per year of 1.45 millisievert (average). Of internal radiation exposure, inhaling radon is 0.45 millisievert per year in Japan, as opposed to the world average of 1.2 millisievert per year.Now, these so-called experts in the government commission are saying the internal radiation from food can be 1 millisievert per year (assuming the life of 100 years), in addition to the natural internal radiation from food (K-40) which is 0.41 millisievert per year. Then, you will have to add internal exposure from inhaling the radioactive materials IN ADDITION TO radon which is 0.45 millisievert per year.
  • Winter in the Pacific Ocean side of east Japan is dry, particularly in Kanto. North wind kicks up dust, and radioactive materials in the dust will be kicked up. The Tokyo metropolitan government will be burning away the radioactive debris from Iwate Prefecture (Miyagi's to follow) into the wintry sky. So-called "decontamination" efforts all over east Japan will add more radioactive particles in the air for people to breathe in.
  • For your information, the comparison of natural radiation exposure levels (the world vs Japan), from the Nuclear Safety Research Association Handbook on treating acute radiation injury (original in Japanese; my translation of labels). Japan has (or had) markedly lower radon inhalation than the world average, and much lower external radiation from the ground and from cosmic ray. It makes it all up by overusing the medical X-rays and CT scans, and even the Nuclear Safety Research Association who issued the following table says Japan tends to use too many X-rays and scans and that the medical professionals should make effort not to overuse them.

15 years old student died of subarachnoid hemorrhage (10 micro Sv/h) [28Oct11] - 0 views

  • In Ichinoseki shi, Iwate, a 15 year old student died of subarachnoid hemorrhage at his junior high school.
  • A subarachnoid hemorrhage, or subarachnoid haemorrhage in British English, is bleeding into the subarachnoid space—the area between the arachnoid membrane and the pia mater surrounding the brain. This may occur spontaneously, usually from a ruptured cerebral aneurysm, or may result from head injury. Symptoms of SAH include a severe headache with a rapid onset (“thunderclap headache”), vomiting, confusion or a lowered level of consciousness, and sometimes seizures. The diagnosis is generally confirmed with a CT scan of the head, or occasionally by lumbar puncture. Treatment is by prompt neurosurgery or radiologically guided interventions with medications and other treatments to help prevent recurrence of the bleeding and complications. Surgery for aneurysms was introduced in the 1930s, but since the 1990s many aneurysms are treated by a less invasive procedure called “coiling”, which is carried out by instrumentation through large blood vessels.
  • SAH is a form of stroke and comprises 1–7% of all strokes. It is a medical emergency and can lead to death or severe disability—even when recognized and treated at an early stage. Up to half of all cases of SAH are fatal and 10–15% of casualties die before reaching a hospital, and those who survive often have neurological or cognitive impairment. SOURCE Though the connection with radiation is not “clear”, radiation level was higher than 10 micro Sv/h at the play ground. The radiation level was not announced to the students and parents. He belonged to a sport club, spent a lot of time at the playground. He fainted inside of the school building. When he was sent to the hospital, he was unresponsive. He died there. At this school, even inside of the classroom, it is over 0.5 micro Sv/h. (Source)

Eastern Japanese are starting to have bruise on their bodies [08Dec11] - 0 views

  • This kind of posts will be “unconfirmed” forever. A Japanese citizen talked about his own symptoms on a Japanese forum. In his case, a bruise appeared on his stomach and it does not hurt even if he touches it. This is only one of the many cases posted on the internet. I expect someone who got through Chernobyl or has radioactive medical knowledge to see this picture. His symptoms are: canker sore Diarrhea ←me too Anemia Vertigo Bleeding from gum High blood pressure Nausea after eating something Itchy eyes ←me too Bad eye sight ←me too Ringing in the ears ←me too Muscle pain even though he did not work out ←me too Sore throat ←me too He suffered from these symptoms until this summer. They still come out on and off. Recently he suffers from constant pain around belly, bowel, and bladder. He analyzes it’s from internal exposure.

Thyroid cancer, fracking and nuclear power [19Jan12] - 0 views

  • Thyroid cancer cases have more than doubled since 1997 in the United States, while deadly industrial practices that contaminate groundwater with radiation and other carcinogens are also rising. New information released by the U.S. National Cancer Institute (NCI) estimates that 56,460 people will develop thyroid cancer in 2012 and 1,780 will die from it.
  • From 1980 to 1996, thyroid cancer increased nearly 300%, while the population increased by (again) 18%. Most thyroid cancers don’t develop for 10-30 years after radiation exposure, but the monstrous spike in thyroid cancer from 1980-2012 is only partly the result of Pennsylvania’s Three Mile Island nuclear accident in 1979 (TMI). Pennsylvania, with its nine nuclear reactors, does have the highest incidence of thyroid cancer across nearly all demographics among 45* states, reports epidemiologist Joseph Mangano, MPH MBA, of the Radiation and Public Health Project. In 2009, he analyzed data from the Centers for Disease Control’s national survey of thyroid cancer incidence for the years 2001-2005 and compared it with proximity to nuclear power stations, finding:
  • M]ost U.S. counties with the highest thyroid cancer incidence are in a contiguous area of eastern Pennsylvania, New Jersey, and southern New York. Exposure to radioactive iodine emissions from 16 nuclear power reactors within a 90 mile radius in this area … are likely a cause of rising incidence rates.

  • Fracking a ‘Dirty Bomb’
  • TMI also can’t explain why the thyroid cancer rate for the four counties flanking Indian Point Nuclear Power Plant in New York was 66% above the national rate in 2001-2005. Other, more subtle sources may also be contributing to hiked thyroid cancer rates, like leaking nuclear power plants and hydraulic fracturing, both of which contaminate air, soil and groundwater with radiation and other nasty chemicals. Indeed, remarking on this, Mangano (who recently co-authored a controversial study with toxicologist Janette Sherman suggesting a link between Fukushima fallout and US cancer deaths numbering from 14,000 to 20,000) said:
  • From 1970-1993, Indian Point released 17.50 curies of airborne I-131 and particulates…. [That] amount exceeded the official total of 14.20 curies released from the 1979 Three Mile Island accident. In 2007, officials that operate the Indian Point plant reported levels of I-131 in the local air, water, and milk, each of which is a potential vector for ingestion. Iodine-131, or I-131, is a radioactive isotope produced by nuclear fission
  • Radiation isn’t released into the environment only via nuclear plants and bombs. Geologist Tracy Bank found that fracking mobilizes rock-bound uranium, posing a further radiation risk to our groundwater. She presented her findings at the American Geological Society meeting in Denver last November.
  • Because of some 65 hazardous chemicals used in fracking operations, former industry insider, James Northrup, calls it a “dirty bomb.” With 30 years of experience as an independent oil and gas producer, he explains: The volume of fluid in a hydrofrack can exceed three million gallons, or almost 24 million pounds of fluid, about the same weight as 7,500 automobiles. The fracking fluid contains chemicals that would be illegal to use in warfare under the rules of the Geneva Convention. This all adds up to a massive explosion of a ‘dirty bomb’ underground.

NYTimes: Radioactivity after atomic bomb only 1000th of that from luminous dial watch -... - 0 views

  • Science with a Skew: The Nuclear Power Industry After Chernobyl and Fukushima
  • [...] The Japanese physicians and scientists who’d been on the scene told horrific stories of people who’d seemed unharmed, but then began bleeding from ears, nose, and throat, hair falling out by the handful, bluish spots appearing on the skin, muscles contracting, leaving limbs and hands deformed. When they tried to publish their observations, they were ordered to hand over their reports to US authorities. Throughout the occupation years (1945-52) Japanese medical journals were heavily censored on nuclear matters. In late 1945, US Army surgeons issued a statement that all people expected to die from the radiation effects of the bomb had already died and no further physiological effects due to radiation were expected. When Tokyo radio announced that even people who entered the cities after the bombings were dying of mysterious causes and decried the weapons as “illegal” and “inhumane,” American officials dismissed these allegations as Japanese propaganda.
  • The issue of radiation poisoning was particularly sensitive, since it carried a taint of banned weaponry, like poison gas. The A-bomb was not “an inhumane weapon,” declared General Leslie Groves, who had headed the Manhattan project. The first western scientists allowed in to the devastated cities were under military escort, ordered in by Groves. The first western journalists allowed in were similarly under military escort. Australian journalist Wilfred Burchett, who managed to get in to Hiroshima on his own, got a story out to a British paper, describing people who were dying “mysteriously and horribly” from “an unknown something which I can only describe as the atomic plague… dying at the rate of 100 a day,” General MacArthur ordered him out of Japan; his camera, with film shot in Hiroshima, mysteriously disappeared.

Report: Fallout from Fukushima coincides with spike in Boise infant mortality rate [25J... - 0 views

  • The aftermath of the tsunami that ransacked the Japanese coast led to one of the worst nuclear meltdowns in the history of the world. Now, two researchers believe it may also have played some role in killing tens of thousands of Americans. “[It’s] 155,000 deaths,” Joseph Mangano said, ”so we’re not talking about an increase from three to five deaths. We’re talking about quite a few.”
  • Mangano works at the Radiation and Public Health Project. The report he co-authored for a medical journal suggesting a link between Fukushima fallout and an increase in deaths in the United States has stirred up some controversy. “The authors appeared to start at a conclusion,” Scientific American’s Michael Moyer wrote, “ – babies are dying because of Fukushima radiation – and work backwards, torturing their data to fit their claims.” But Mangano said his critics miss the point.
  • “We have not stated conclusively that Fukushima fallout killed 22,000 Americans,” he said. Instead, he and co-author Dr. Jannette Sherman cite numbers from the U.S. Centers for Disease Control and Prevention's weekly morbidity report. That data showed a large spike in deaths – particularly infant deaths – in the 14 weeks following the Fukushima meltdown.

Fukushima health concerns [08Nov11] - 0 views

  • As efforts to end the nuclear disaster at Tokyo Electric Power Co.'s Fukushima No. 1 nuclear power plant drag on, it is important for the central and local governments to step up their efforts to closely examine the health conditions of people concerned and to decontaminate areas contaminated by radiation.
  • The people who have been most affected by radiation from the Fukushima plant are workers, both from Tepco and from subcontractors, who have been trying to bring the radiation-leaking plant under control. In the nation's history, these workers rank second only to the victims of the atomic bombings of Hiroshima and Nagasaki in terms of their exposure to radiation, therefore the possibility cannot be ruled out that they will develop cancer. Tepco and the central government must do their best to prevent workers' overexposure to radiation and take necessary measures should workers become overexposed to radiation. It is of great concern that little has been disclosed regarding the conditions of the workers at the Fukushima No. 1 nuclear power plant. Tepco and the central government should disseminate information on the actual working conditions of these people, even if such information seems repetitious and includes what they regard as minor incidents. People are forgetful. They need to be informed. Such information will help raise people's awareness about the issue of radiation and its impact on health.
  • It must not be forgotten that exposure to radiation has long-term effects on human health. In the Hiroshima and Nagasaki atomic bombings, the number of leukemia cases started to increase among bombing survivors two years after the bombs were dropped. In the case of the 1986 Chernobyl accident, thyroid cancer began to appear among children several years after the disaster happened. Particular attention should be paid to the health of children. In view of these facts, it is logical that the Fukushima prefectural government has developed a program to monitor the health of all residents in the prefecture, who number about 2 million, throughout their lifetime. It has also started examining the thyroids of some 360,000 children who are age 18 or younger. Detailed and long-term area-by-area studies should be carried out to record cancer incidences. In August, the Nuclear Safety Commission of Japan estimated that the Fukushima accidents released a total of 570,000 terabecquerels of radioactive substances, including some 11,000 terabecquerels of radioactive cesium 137.
  • ...3 more annotations...
  • But a preliminary report issued in late October, whose chief writer is Mr. Andreas Stohl of the Norwegian Institute for Air Research, estimates that the accidents released about 36,000 terabecquerels of radioactive cesium 137 from their start through April 20. It is more than three times the estimate by Japan's Nuclear Safety Commission and 42 percent of the estimated release from Chernobyl. On the basis of measurements by a worldwide network of sensors, the report says that 19 percent of the released cesium 137 fell on land in Japan while most of the rest fell into the Pacific Ocean. It holds the view that a large amount of radioactive substances was released from the spent nuclear fuel pool of the No. 4 reactor, pointing out that the amount of radioactive emissions dropped suddenly when workers started spraying water on the pool.
  • The report reinforces the advice that local residents in Fukushima Prefecture should try to remember and document in detail their actions for the first two weeks of the nuclear disaster. This will be helpful in estimating the level of their exposure to radiation. But it must be remembered that sensitivity to radiation differs from person to person. It may be helpful for individuals to carry radiation dosimeters to measure their exposure to radioactive substances. As for internal radiation exposure from food and drink, the Food Safety Commission on Oct. 27 said that a cumulative dose of 100 millisieverts or more in one's lifetime can cause health risks. But when it had mentioned the limit of 100 millisieverts in July, it explained that the limit covered both external and internal radiation exposure. Its new announcement means that the government has not set the limit for external radiation exposure. It also failed to clarify whether the new dose limit is safe enough for children and pregnant women
  • The day after the commission's announcement, health minister Yoko Komiyama said the government will lower the allowable amount of radiation in food from the current 5 millisieverts per year to 1 millisieverts per year. The new standard will be applied to food products shipped in and after April 2012. The government will set the amount of allowable radioactive substances for each food item. The health ministry estimates that at present, internal radiation exposure among various age groups from food in the wake of the Fukushima No. 1 accidents is about 0.1 millisieverts per year on the average and that if the new standard is enforced, the lifetime radiation dose will not exceed 100 millisieverts. It is important for the central and local governments to establish a system to closely measure both outdoor radiation levels and radiation levels in food products and to take necessary measures. In areas near Fukushima No. 1 power plant, many hospitals' functions have weakened because doctors and nurses have left. Urgent efforts must be made to beef up medical staffing at these hospitals.

The difference between types of radiation [28Jul11] - 0 views

  • Radiation from nuclear accidents is frequently expressed by the media as “just like an x-ray” or “equivalent to an x-ray”. This comparison is grossly incorrect. Many times internal exposure will be again, incorrectly compared to an x-ray. These faulty comparisons give the public a false sense of security. The International  Physicians for the Prevention of Nuclear War have an excellent paper that clearly explains the differences between medical diagnostics and a nuclear accident.
