How contaminated a bird is in Fukushima2

 

Prof. Mori of Tokyo university took a picture of a bush warbler in Fukushima by autoradiography.
It took one month to capture the radiation from cesium 137.
The bush warbler was found dead in Iidate mura last December.
This photo was taken from the stomach of the bird. Black spots in the wing parts show radioactive particles stuck to the wings. The ones in the body parts show the radioactive particles taken into the body. Biological concentration is assumed to have happened through contaminated worms.

 
先日、森敏先生から以前お願いしていたラジオオートグラフの写真が届いた。
私が飯舘村で昨年12月に採取してきたウグイスの死骸だ。
やはりだいぶ被曝していた。

ウグイスの被曝の状況を映像化したものだ。
カラーはサンプルの写真。
モノクロのレントゲン写真のようなものがラジオオートグラフ。
黒い点々としたものがCs137の放射線がでているため黒くなった。
羽の部分は表面に付着したもの、腹の部分の黒くなったところはお腹の内部から放射線がでている。
汚染した虫などを食べたことで食物連鎖で濃縮されたものと思われる。
これはお腹側を羽を広げて撮影したものだ。
1枚の写真を撮影するために要した感光時間は一ヶ月。

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.
