Radioactivity density of the seawater is increased at 57% of tested locations offshore Fukushima

On 11/26/2012, Tepco released the report about radioactivity density of the seawater at 21 points from offshore of Miyagi to offshore of Fukushima.

The result shows at 12 of 21 locations (57%), radioactivity density of seawater increased from early September to mid October.

La concentration de la radioactivité dans l’eau de mer au large de Fukushima a augmenté de 57 %

Le 26 novembre 2012, Tepco publie un rapport sur la concentration de la radioactivité dans l’eau de mer prise au large en 21 points s’étalant de Miyagi à Fukushima.

Les résultats montrent que sur 12 des 21 points (57 %), la concentration de radioactivité dans l’eau de mer a augmenté entre septembre et mi-octobre.

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.
