(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.

  • 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 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.
  • ...14 more annotations...
  • 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.
  • 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.
  • 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.
  • 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.
  • 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

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.

Bird numbers plummet around stricken Fukushima plant [03Feb12] - 0 views

  • Researchers working around Japan's disabled Fukushima Daiichi nuclear plant say bird populations there have begun to dwindle, in what may be a chilling harbinger of the impact of radioactive fallout on local life. In the first major study of the impact of the world's worst nuclear crisis in 25 years, the researchers, from Japan, the US and Denmark, said their analysis of 14 species of bird common to Fukushima and Chernobyl, the Ukrainian city which suffered a similar nuclear meltdown, showed the effect on abundance is worse in the Japanese disaster zone.
  • The study, published next week in the journal Environmental Pollution, suggests that its findings demonstrate "an immediate negative consequence of radiation for birds during the main breeding season [of] March [to] July".Two of the study's authors have spent years working in the irradiated 2,850 sq metre zone around the Chernobyl single-reactor plant, which exploded in 1986 and showered much of Europe with caesium, strontium, plutonium and other radioactive toxins. A quarter of a century later, the region is almost devoid of people.
  • Timothy Mousseau and Anders Pape Moller say their research uncovered major negative effects among the bird population, including reductions in longevity and in male fertility, and birds with smaller brains.Many species show "dramatically" elevated DNA mutation rates, developmental abnormalities and extinctions, they add, while insect life has been significantly reduced.

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.

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.

Devastating nuclear bomb only an ocean away - Analysis, Opinion - Independent.ie [25Nov01] - 0 views

  • Sellafield could become a deadly weapon, capable of contaminating Irish people with cancer, warns Aine O'ConnorIN THE Eighties the world worried about the possibility of nuclear war. The deployment of nuclear weapons was at its height, relations between the superpowers at their worst. All things nuclear posed a threat and as a by-product, Sellafield became a household name.
  • We learned that the Irish Sea was the most radioactive in the world, that mutated fish had been found in it, that there were serious health concerns in Co Louth and that an accident at Sellafield would have serious repercussions for our health.
  • The Norwegian Government is also considering legal action since radioactive pollution from the plant has been found along the Norwegian coastline as far north as the Arctic.

  • The recent Safety at Sellafield conference in Drogheda heard that the greatest risk to Irish people from a disaster at Sellafield would be of long-term cancers.
  • On October 22, an EU report commissioned before September 11 identified a risk of sabotage and claimed the UK authorities have not complied with the responsibilities outlined in the Euratom Treaty: that some emissions from the plant have caused radiation doses in excess of the recommended EU levels and that the European Commission has never effectively used its rights to inspect the plant.
