Tritium spreads underground of Fukushima plant

 

1.6E+6 Bq/m3 of Tritium was measured from a deep well in the plant area of Fukushima (500m away from the reactor buildings), Tepco announced in their press conference of 4/4/2012.

Last time they measured beta nuclides from the same well on 11/19/2011, tritium was ND, which shows the underground contamination has been expanding since then.

From the press release of 4/4/2012, Tepco measured 1.3E+6 Bq/m3 of tritium from the sub drain of reactor 2, and 1.8E+6 Bq/m3 from the one of reactor5, which are the same level as what they measured from the deep well.
As to tritium, underground water is as contaminated as sub drain of reactors.

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.
