Approach of radiation protection on recycling materials contaminated by radionuclides

Miwa, Kazuji ; Iimoto, Takeshi*

ICRP Publ.103 shows that reference levels are used for radiation protection of public exposure in existing exposure situation. However, there is no specific description about actual operation of reference levels. There is a possibility that a more rational radiation protection concept can be applied depending on the scale of environmental pollution in the existing exposure situation. This study proposes variation of radiation protection concept for public exposure assuming reusing radiation contaminated material which is in existing exposure situation.
