Radioactive particles circulate the world taking 40 days

 

Following up this article..Cesium fallout spikes every 40 days

NHK reported the full study of Prof. Watanabe, which Yomiuri newspaper missed.
The researching group of Prof. Watanabe assumes the radioactive particles circulate the world taking 40 days.

They measured 0.0048 Bq/m3 of cesium in May 2011, but it was 0.0007 Bq/m3 this March.
The radioactive particles travel around the world and fall off to the ground to decrease its concentration.

Prof. Watanabe comments, they can trace how radioactive particles spread over the world and how to affect each country on its path.

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.
