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.
