<セシウム検出>ビニールハウス土から5.8万ベクレル
毎日新聞 2月13日(月)21時16分配信
千葉県などが出資する第三セクター「千葉園芸プラスチック加工」(同県東金市)は13日、同県内の農家から集めた使用済みビニールハウスのリサイクル過程で出た土から、国の埋め立て基準1キロ当たり8000ベクレルの7倍を超える最大5万8000ベクレルの放射性セシウムを検出したと発表した。同社は周辺の園芸農家に搬出した土計約140トンを回収し、敷地内に保管する予定で、「原発事故後の風雨の影響で、放射性物質を含む土がビニールの表面に付着した影響ではないか」と説明している。

同社は、回収したビニール類についた土とビニールを分け、洗浄、熱処理などし、リサイクルしている。取り除かれ、施設内に保管した土の周辺の空間放射線量を1月に計測したところ、高い数値が出ていた。

同社がさらに調べたところ、工場内の土から1キロ当たり2万2400ベクレル、東金市内の園芸農家の畑7カ所に搬出した土からも同260~5万8000ベクレルの放射性セシウムを検出した。畑はいずれも植木用で、食用の農作物は作っていないという。

同社の担当者は「認識が甘く、深く反省している。今後は定期的に検査をし、管理を徹底したい」と話した。【森有正】

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.
