新潟県十日町市は２２日、市が保育施設の土壌などの放射性物質調査を行った結果、市立白梅保育園で雨水を 集める槽にたまった泥から１キロ・グラム当たり１万８９００ベクレル、私立愛宕幼稚園で草葉の堆積物から同２万７０００ベクレルの放射性セシウムが検出さ れたと発表した。
Tokamachi City in Niigata Prefecture announced on August 22 the result of the survey of radioactive materials in the soil in nursery schools and kindergartens in the city. 18,900 becquerels/kg of radioactive cesium was found in the sludge at the bottom of the container that collects rainwater at a public nursery school, and 27,000 becquerels/kg of radioactive cesium was found in the yard compost pile at a private kindergarten.
If the level of radioactive cesium exceeds 8,000 becquerels/kg up to 100,000 becquerels/kg, it has to be temporarily stored at a controlled processing plant. The city will consult the prefectural government as to how to dispose the sludge and the yard compost.
The samples were taken on August 12, and tested at a testing laboratory in Niigata. At both locations, the air radiation levels at 1 meter above the ground was 0.10 microsievert/hour and 0.14 microsieverts/hour, both of which were within the normal range.
