Of the asbestos-containing wastes arising from the dismantling activities of nuclear facilities, those with radioactive concentrations that do not need to be treated as radioactive materials will be cleared from the nuclear regulatory control. Those will be disposed of or recycled as specially controlled industrial waste based on the Waste Management and Public Cleansing Act. The authors constructed evaluation scenarios according to the treatment manual for asbestos-containing wastes, and evaluated radioactive concentrations (clearance level) of 33 radionuclides corresponding to the public exposure dose of asbestos waste of 10 μSv/y. As a result, the evaluated concentration values were equal to or higher than the current clearance level. It was confirmed that the current clearance level could be applied for asbestos-containing wastes.
