340,000 Bq/kg of cesium from the dam in Fukushima

 

Following up this article ..Snowmelt will carry the radiation stocked in mountain
Ministry of the Environment measured radiation at 214 points of the rivers and lakes in Iwate and Fukushima.
They measured 340,000 Bq/kg of cesium from the soil of Ogaki dam in Namie machi.

This is the second survey of them, and the contamination has become worse at some locations.
MOE states highly contaminated soil may have flew into the dams by rain water.

Even by the Japanese low, soil of 340,000 Bq/Kg of cesium has to be kept in shelter with reinforced concrete and separated from rain water.

大柿ダム周辺セシウム34万ベクレル 浪江
2012年2月18日 | カテゴリ: 福島第一原発事故

環境省は17日、岩手、福島両県の河川や湖など計214地点で測定した土壌などに含まれる放射性物質の濃度を公表。東京電力福島第一原発事故の警戒区域にある浪江町の大柿ダム周辺の土壌で、最大一キロ当たり34万ベクレルの放射性セシウムを検出した。

環境省が行った本県全域での調査は2回目。福島県内の河川や湖では前回調査よりも数値が高い地点があり、同省は「雨で比較的高濃度の土壌が流れ込んでたまった可能性がある」としている。

10万ベクレルを超える一般ごみの焼却灰などは、鉄筋コンクリートの仕切りや雨水流入防止設備も備えた処分場に埋め立てる必要があり、34万ベクレルはそれを上回る水準。

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.
