摘　　要：为对辐射照射源或人为活动实施风险管理,有效降低环境放射性水平及辐射照射危害,基于我国癌症基线发病率和由人口普查数据计算获得的寿命表,采用国际放射防护委员会(ICRP)推荐的辐射致癌危险预测估算方法和模型参数,估算得到了我国辐射致癌超额危险系数,为6.98×10^(−2)Sv^(−1);进而利用国际原子能机构推荐的个人剂量限值,通过放射性污染物的健康风险表征模型计算辐射致癌可接受风险标准,鉴于我国辐射致癌高背景风险、癌症基线发病率和社会经济发展水平,确定我国辐射照射致癌可接受风险标准范围为3.0×10^(−5)~3.0×10^(−3)。In order to manage the risk of radiation sources or human activities and effectively reduce the level of environmental radioactivity and radiation exposure hazards,the Chinese radiation carcinogenesis excess risk coefficient was estimated based on the cancer baseline incidence rate of China and the life table derived from the census data,using the radiation carcinogenic risk estimation methods and model parameters recommended by the International Commission on Radiological Protection(ICRP).The calculated value was 6.98×10^(–2) Sv^(–1).By applying the personal dose limit recommended by the International Atomic Energy Agency(IAEA),the acceptable risk criteria of radiation carcinogenesis were calculated through the health risk characterization model of the radioactive contaminants.The acceptable risk level of radiation carcinogenesis in China was established at 3.0×10^(–5)-3.0×10^(–3),considering the high background risk of radiation carcinogenesis,cancer baseline incidence rate,and social and economic development level.
