180,000 Bq/m3 of tritium from groundwater of Fukushima plant area

Following up this article..Tepco plans to pump up groundwater and discharge it to the sea

From the priority measurement of radiation, tritium was detected from groundwater at one of the sampling locations.

The first measurement was conducted on 2/21~22/2012, the second one was conducted on 5/24/2012.

14.7 ~ 13.9 O.P.m and 25.7 ~ 18.1 O.P.m indicate the height from the near sea level of where the sample was taken.

Also, it’s in the increasing trend from 2/21~22/2012. The highest reading was 180,000 Bq/m3.

Tepco states it’s still low level for the concentration of notice, which is 60,000,000 Bq/m3 but it’s not announced what this figure is based on.

The location to take the sample is higher than nuclear buildings, Tepco assumes Tritium leaked as evaporated water from the reactors, fell on the ground and sank into underground.

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.
