摘　　要：辐射环境影响评价是低放废物暂存库辐射环境监管的重要内容。为掌握我国典型低放废物暂存库辐射水平,根据满负荷运行状态下低放废物暂存库源项及辐射屏蔽设计参数,运用点核积分方法给出周围辐射剂量率水平,计算工作人员及公众经外照射途径所致辐射剂量;并对低放废物暂存库辐射水平进行监测,估算所致工作人员以及公众受照剂量,同时对工作人员个人年累积剂量资料进行复核。结果表明,点核积分方法计算结果能满足屏蔽设计及辐射环境监管要求,理论计算和实际测量相互验证,工作人员及公众受照剂量均满足剂量限值要求。Radiation environmental impact assessment is an important aspect of radiation environmental supervision for low level radioactive waste storage facilities.In order to get the radiation level of typical low level radioactive waste temporary storage facilities in China,based on the source term and radiation shielding design parameters of the low level radioactive waste temporary storage facility under full load operation,the point kernel integration method is used to provide the surrounding radiation dose rate level,and calculate the radiation dose caused by external exposure routes for workers and the public;And monitor the radiation level of the temporary storage of low-level radioactive waste,estimate the radiation dose to the staff and the public caused,and review the personal annual cumulative dose data of the staff.The results show that the calculation results of the point kernel integration method can meet the requirements of shielding design and radiation environment supervision.Theoretical calculations and actual measurements are mutually verified,and the exposure dose to both staff and the public meets the dose limit requirements.
