摘要

Fukushima residents have expressed strong concern about large areas contaminated by radionuclides from the Fukushima Daiichi Nuclear Power Plant Accident. During the more than four-year aftermath, decontamination has continued, but the use of radionuclide-contaminated soils from road maintenance is prohibited by law. Indeed, road maintenance cannot be conducted in Fukushima because no disposal method can be used for radionuclide-contaminated soils from road maintenance. Recent studies of radionuclide-contaminated soils show that silt and clay mainly adsorb radioactive cesium. Therefore, classification of silt and clay from radionuclide-contaminated soils can reduce the amounts of contaminated soil and radioactive wastes. This study investigates the applicability of a soil washing method to classify silt and clay from radionuclide-contaminated soils and to reduce radioactive concentrations of soils from road maintenance.
