以国内外相关数据调研和典型厂址测算相结合的方式,对放射生态转移参数、生物剂量转换因子和生物辐射剂量筛选水平进行研究,为核电厂环境影响报告书相关专题的编制提供支持性材料,为国家环境保护主管部门的决策提供参考依据。首先,以国内在建彭泽核电厂和海阳核电厂为典型厂址,开展典型厂址的放射生态转移参数和生物剂量转换因子的研究。在厂址采集水、选定生物和底泥样品,用中子活化分析方法对样品中的稳定元素Cs、Ba和Co浓度进行测量,计算各厂址选定生物的浓集因子CF和沉积物分配系数Kd
Based on the domestic and international data research and typical site measurement, the paper studies the radiation ecological transfer parameters, biological dose conversion factor and biological radiation dose screening level to provide supporting materials for the preparation of relevant topics of the nuclear power plant environmental impact report, Provide reference for the decision-making of the national environmental protection department. First of all, taking the domestic construction of Pengze Nuclear Power Plant and Haiyang Nuclear Power Plant as typical sites, the study conducted a study on the radiation ecological transfer parameters and biological dose conversion factors of typical sites. Water, selected samples of biological and sediment were collected at the site and the concentrations of Cs, Ba and Co, the stable elements in the samples, were measured by neutron activation analysis. Concentration factors CF and sediment partition coefficients of selected organisms at each site were calculated Kd
