バンダジェフスキー博士7月21日東京専門家用講演会メモ下書き Bandazhevsky Seminar in Tokyo July 2013
As a matter of fact, Cs 137 was detected right after the operation of nuclear power plant, but the promoters kept saying, "it is safe."
Cs emitts beta and gamma rays while decaying into Barium, which is highly toxic. There are many papers which shows the toxicity of Ba, too. Especially, when Ba gets into the cells, they are very risky.
Cs has chemical toxicity along with radioactive toxicity.
Internal exposure is much more dangerous than external exposure.
However, international organizations are calculating the risk of internal radiation based on the external one.
They say, 1 mSv (equivalent to 600~700Bq/kg) is harmless, but there are health impacts under much lower levels.
No laboratories have been conducting the studies of internal radiation, since that would prove the danger.
Let me briefly introduce my personal history.
When I started my study in Gomel in 1990, I was already a University professor.
My expertise was originally "congenital malformation."
I founded the Gomel Medical University and started my study.
Gomel was a contamianted area and doctors fleed from the city.
Therefore, I continued my research while I was a rector at Gomel Medical University.
In those days, I didn't have any prejudice on radiation effects and simply tried to search for the causes of diseases among the residents.
I established a Cs monitoring system for residents.
(In those days, nobody was doing that and some Belarus companies cooperated for that.)
After my research, nobody in Belarus, Russia, or Uklaine has done a similar research.
Though vast amount of money is being used for reconstruction of Chernobyl, there is almost nobody who can talk clearly on health impacts.
The former Soviet Union used various ways to conceal the data of contamination, and residents ate contaminated food without knowing it.
For example, stored beef at Gomel station was contaminated but it was distributed all over the country, and of course the residents didn't know about it.
So I checked the Cs body concentration of kids both in Gomel and uncontaminated areas, and found kids in both areas were contaminated.
I was known as the rector of Gomel Medical University in the local society, but when I started my research, local municipal officers started to be away from me.
One day, I gave my rearch paper to the Minister of Health, then he just put my paper in his desk drawer. I also sent the same to the goverment.
After that, oppression started against me.
There is so called reference level for food, but it is wrong to say that the food is safe if it is under the reference level.
For example, milk cannot be safe at the level of 100Bq/l. The inspector does not say the sample was 98 Bq/l and children drink it without knowing it.
If the child keeps drinking that milk for several days, considerable amount of radioactive materials can be accumulated in his/her body. Can you call this is safe? This is solely a fake declaration of safety.
The most important thing is to make decisions to protect people from now on rather than pointing out the past mistakes done by the politicians.
But after the accident, the real situation of contamination had been concealed. Even the accident itself was concealed and on May Day festival, residents including children were mobilized for parades.
After I had been imprisoned for 8 years (I was actually writing in the prison and the book was published in France), I was ousted from my own country since 2006, and had been staying in France for several years.
Everyone asked for my autography in the book I published in France (the one I wrote about the issue of radiation and my thoughts while I was in the prison), but I was wondering whether he/she understood what I wrote.
In 1964, already 450 pCi/kg Cs was detected in soil, which became 50 pCi/kg in 1969.（Marey AN、 et al 1974）
However, the book disappeared from major libraries after the accident.
The book said, "contamination of this level has no risk, but if there is any additional radiation contamination, there should be some urgent measures to be implemented."
The book was found by a strudent in a small library in Gomel. After that, I used that data in official places and cited the figures in the Parliament of Belarus. Then, the chairman of the Parliament said that special attentions should be paid to the rector of Gomel Medical University and several months later, I was dismissed.
In Russia, even now, the figures have been concealed.
Several months ago, when I said in an interview by a Russian reporter, "There had already been contamination even before Cheronobyl," that statement was omitted from the article. The chief editor told me that my statement was not credible since there wasn't the book in any library in Russia.
However, the figure is listed on my official site, chernobyltoday.org, where many people can take a look.
What is the people in the authority side scared of ? They kept saying that nuclear power is nothing to be worried about, but if the data before the accident is relased, their statement could be proven to be false.
The same thing can be said about IAEA. They say the contamination started only after the Cheronobyl.
In Belarus, the contaminated area in 1974 coincides with the contaminated area since 1986. This information is very important.
Even some people in our side tell me not to talk about the contamination before Chernobyl, since contamination from Chernobyl could be underestimated.
However, I cannot keep silence on the contamination of these areas before the Chernobyl accident.
These areas had been contaminated for 50 years including the years before the Chernobyl accident.
As for cardiovascular diseases, some institutes in Belarus tell the doctors not to write in the medical record.
But in contaminated areas, ischemic heart disease is high.
Cancer incidence rates are higher in rural areas than urban areas, because people in rural areas eat contaminated food more.
Of course, that doesn't mean that urban areas are safe.
While I was living in Belarus, I was eating normally, and I got sick. I bought a lot of blueberries in Minsk, the capital of Belarus. I thought these blueberries were from some surburb of Minsk.
I had food poisoning symptoms several times after eating blueberries (I thought I had food poisoning), but I later knew that the berries came from contaminated areas.
When I checked my body Cs concentraion in Iwankov District in Ukraine, my figure was higher than the local residents, since I had been eating contaminated food.
Cs concentrates more among children.
Especially, accumulation in thyroid is high, so there is a high possibility that Cs is contributing to thyroid cancer. This issue should needs further studies.
For example, children born after year 2000 did not get initial exposure, but there are many thyroid cancer children.
It is very important to know that radioactive iodine is not the sole contributor to thyroid cancer.
There is a possibility that thyroid cancer will be increased from food contamination in Fukushima.
Cs concentration level result coincided between animal experiments and those of human beings. Internal organ's concentration was much higher compared with the average per kg per body.
In a textbook by former Soviet Union, Cs is supposed to accumulate in skeletal muscle, without any further explanation. That is true since the weight of skeletal muscle is much, but as for the concentration, internal organs such as heart is higher.
However, there was nobody who checked the Cs concentration in internal organs.
The screen shows aminal experiments carefully prepared.
Injection of radioactive material into a rat.
Measuring the body concentration
Preparing tissue samples of internal organs
The tissue is separated for paraphine block
The scene shows the mortuary
Organs were extracted after dissection
Heart and other organs are placed on the plate.
Sampling of the heart is prepared.
Measuring how much radioactive materials are accumulated in the heart
(Measureing was done in a lead container)

Mitochondoria (producer of cell energy) structure was altered and multiple number of mitochondorias were joined.
