165,000 Bq/Kg from Fukushima river soil

Rivers gone dead.
Ministry of the environment conducted radiation tests at 120 points of rivers in Fukushima prefecture. The test was done from 4/29 to 6/20/2012.
The highest reading was 165,000 Bq/Kg from the river bottom soil of Ukedogawa river in Namie machi, where is in Hazard area.

According to Ordinance of the Ministry of Economy, Trade and Industry No.112 [Link], radioactive material to contain more than 100 Bq/kg of Cs-134/137 must be properly stocked to not to cause public radiation hazard.
This is 1,650 times higher than the safety limit.

They also measured 2 Bq/L of cesium from Abukuma river, but this is lower than 2.7 Bq/Kg from well water in Chiba. It needs to be verified if Fukushima river is actually cleaner than well water in Tokyo area.(cf. 2.7 Bq/kg of cesium measured from well water at 25km from the center of Tokyo)





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.
