23,300 Bq/Kg of cesium from 4km of filter plant

 

Members of Japanese communism party measured 23,300 Bq/Kg of cesium from the soil of Mizumoto park in Katsushika ku Tokyo.

The measurement was done at 4 points in February.
They measured 7,770 ~ 23,300 Bq/Kg from soil and 1,180 ~ 8,290 Bq/Kg from dead leaves.
Tokyo local government decided not to even decontaminate the place because the radiation level was lower than 1 microSv/h at 1m height above the ground.

There is a water purifying plant “Kanemachi josuijo” 4km away from the park.

土壌からセシウム2万ベクレル=葛飾区の都立公園で―共産党都議団調査
時事通信 2月21日(火)18時14分配信
共産党東京都議会議員団は21日、都立水元公園(葛飾区)の野鳥観察舎入り口などの土壌から、最高で2万3300ベクレルの放射性セシウムを検出したと発表した。がれき焼却灰についての国の埋め立て基準は、放射性セシウムが1キロ当たり8000ベクレル以下とされている。
同都議団は2月、野鳥観察舎入り口やドッグラン南東側など4地点で、土壌や落ち葉の放射性セシウムを測定。土壌は1キロ当たり7770~2万3300ベクレル、落ち葉は同1180~8290ベクレルを検出したという。
同都議団は土壌や落ち葉の放射性セシウム測定と除染を都に要請。これに対し都は「昨年11月にこの公園で空間放射線量を測定したが、文部科学省のガイドラインで除染を求める数値(地上1メートルで毎時1マイクロシーベルト以上)は超えておらず、対応する考えはない」(環境局)としている。

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.
