(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:

German Scientist - No Way To Stop Melted Fuel [06Dec11] - 0 views

  • Dr. Sebastian Pflugbeil, the chairman of German Society of Radiation Protection had a lecture in Berlin,and talked about Tokyo. To the question about what we can do to minimize the damage of the accident, he answered: “Nothing. There is no way to stop the nuclear fuel that has melted-through leaking. All we could do is to pray for the fuel not to touch the underground water vein. We must avoid internal exposure from contaminated food. Authorities are trying to make Japanese eat polluted food for their twisted patriotism, but on the other hand, citizens are setting up independent labs around Japan. This is very important. However, lab facility costs are huge. Maintenance, recording the data costs too. Now, the best thing Germans can do is to support those independent facilities financially.”
  • To another question “How dangerous Tokyo is now?” He answered: “Tokyo is not the safe area. Now Tokyo is in the similar situation to Kiev in Chernobyl. Ukrainian Government couldn’t define that densely populated area, Kiev, as evacuating area so they did not admit Kiev was threatened and manipulated the radiation map to look like Plutonium stopped just before Kiev.” Around in Kiev, there were 11 million children in 1990, and now there are 8 million. However, the number of deformed babies is the same, which means the ratio of deformation is increasing. Low dose exposure obviously affects DNA. Only 10 % of babies sent to Kiev hospital can live longer than 1 year.

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.

"I am shaking with anger" says head of University of Tokyo's Radioisotope Center before... - 0 views

  • Professor Tatsuhiko Kodama of Tokyo University Tells the Politicians: “What Are You Doing?”, EX-SKF, July 28, 2011:
  • So, using our knowledge base at the Radioisotope Center, we calculated. Based on the thermal output, it is 29.6 times the amount released by the nuclear bomb dropped on Hiroshima. In uranium equivalent, it is 20 Hiroshima bombs. What is more frightening is that whereas the radiation from a nuclear bomb will decrease to one-thousandth in one year, the radiation from a nuclear power plant will only decrease to one-tenth.
  • n other words, we should recognize from the start that just like Chernobyl, Fukushima I Nuke Plant has released radioactive materials equivalent in the amount to tens of nuclear bombs, and the resulting contamination is far worse than the contamination by a nuclear bomb. [...] As I said before, there was only one geiger counter in Minami Soma City when we went there in May. In fact, there were 20 personal survey meters provided by the US military. But no one at the city’s Board of Education could understand the English manual until we went there and told them how to use them. That’s how it is there.
  • ...4 more annotations...
  • As to the food inspection, there are more advanced survey meters than germanium counters, such as semiconductor detectors. Why doesn’t the Japanese government spend money in supporting (the development of these advanced detectors?)? After 3 months, the government has done no such thing, and I am shaking with anger.” [...]

Tamil Nadu anti-nuclear plant protest turns violent, 6 'bashed up' [15Oct11] - 0 views

  • The agitation against Kudankulam Nuclear Power Plant turned violent on Thursday night as police ‘bashed up’ six physically challenged persons sitting in fast at the project site. The activists of People’s Movement against Nuclear Energy intensified their agitation from Friday morning which literally brought all works in the reactors to a grinding halt . Tamil Nadu is witnessing a rare kind of agitation with the civilian population in Tirunelveli expressing their solidarity with the anti-nuclear activists in their demand for the closure of the KNPP. “No works could be done as scientists and technicians were not allowed inside the KNPP by the agitators. The district administration is taking stock of the situation and we are waiting for words from them,” N K Balaji, project director, KNPP, told DNA. He said the emergency works inside the reactors were being done with a team of skeleton staff.
