5 mSv of exposure may increase the cancer risk as double as average

5 mSv of exposure may increase the cancer risk as double as average

 

Prof. Miyao from Information technology center, Nagoya university found out the low level of exposure may cause high risk of cancer.
Radiation effects research foundation holds the data of 58,000 victims of Hiroshima.
Prof. Miyao compared this data to 1,940,000 of un-exposed people living in Hiroshima and Okayama in 1971. They were 0~34 years old when Hiroshima was damaged.

As the result,

0.005 ~ 0.1 Sv of exposure :

120~130 % risk of Solid Tumors
170~270% risk of liver cancer
180~200% risk of uterus cancer
It’s not known how stress worked.

低放射線も高いがん死亡率 非被爆者と比較調査

広島で被爆した人のうち、浴びた放射線が少量で健康に影響が少ないとされた人でも、被爆していない人よりがんで死亡する率が高いことが、名古屋大情報連携基盤センターの宮尾克教授(公衆衛生学)らの研究グループの4日までの疫学調査で分かった。

研究結果は、9月15日発行の日本衛生学会の英文雑誌で発表する。

同グループは、放射線影響研究所(放影研)が調査している広島での被爆者約5万8000人のデータを、1971年当時の広島、岡山両県の住民で原爆投下時に0-34歳だった非被爆者計約194万人と同じ年齢構成などになるよう補正した。

その上で、被爆者を被ばく線量によって極低線量(0・005シーベルト未満)、低線量(0・005-0・1シーベルト未満)、高線量(0・1シーベルト以上)に区分。それぞれの各種がん死亡率を非被爆者のものと比較した結果、極低、低線量の被爆者は非被爆者よりも固形がん(白血病など造血器系を除くがん)で1・2-1・3倍高く、肝がんでは1・7-2・7倍、子宮がんは1・8-2倍高かった。

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
