摘　　要：本文介绍了气载流出物与液态流出物排放所致公众剂量的计算模式与方法,分析了2013—2020年中国东北某运行核电厂流出物排放对周围公众造成的最大个人有效剂量、关键居民组、关键照射途径、关键核素与核电厂80 km范围内集体有效剂量以及各年度流出物归一化排放量,并与相关标准要求进行了对比。结果表明:通过对各年度《辽宁红沿河核电厂流出物与环境监测评价年报》和《辽宁红沿河核电厂辐射剂量影响评价报告》的数据分析及核算,该核电厂流出物排放致公众剂量远低于国家标准、环境影响报告书及生态环境部批复的年排放限值,各年度流出物排放对周围公众造成的影响很小。This paper introduces the calculation model and method of public doses caused by the discharge of airborne effluents and liquid effluents.Key exposure pathways,key nuclides,collective effective doses within 80 km of the nuclear power plant,and the normalized emissions of effluents in each year were analyzed,and were compared with the relevant standard requirements.The results show that:According to the data analysis and accounting of the Environmental Monitoring and Evaluation Annual Report and the Radiation Dose Impact Evaluation Report of the Nuclear Power Plant,the public dose caused by the radioactive effluent discharge from the nuclear power plant is far below the national standard,the environmental impact report and the annual emission limit approved by the Ministry of Ecology and Environment.The annual effluent discharge has little impact on the surrounding public.
