0.27 μSv/h alpha ray on the roof of Minamisoma city hall

0.17 μSv/h alpha ray on the roof of Minamisoma city hall

 

Mr. Oyama, Minamisoma city councilor measured alpha ray on the roof of Minamisoma city hall.

南相馬市市会議員の大山こういちさんが市庁舎屋上のα線測定を行いました。

The city hall has 4 floors.

市庁舎は4階建てです。

↓ On South side, it was 20 cpm (0.17 μSv/h) of alpha ray. 南相馬市庁舎南側で20 cpm (0.17 μSv/h)のα線を測定

↓ On the north side, it was 32 cpm (0.27 μSv/h) of alpha ray. 同じく北側では 32 cpm (0.27 μSv/h)のα線を測定しました。

Plutonium was not supposed to fly away because it’s heavy, but at least it reached over  the  4th floor of Minamisoma city hall.

プルトニウムは重いので飛ばないはずでしたが、4階建て市庁舎の屋上でも計測されているようです。

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.
