摘　　要：城市放射性废物库是保障核技术利用放射性废物安全贮存的重要公益性环保设施。为合理估算城市放射性废物库辐射环境影响,评估职业工作人员及公众的受照剂量,以某省新建城市放射性废物库为例,开展辐射环境影响剂量计算。结果表明,职业工作人员与公众最大年有效剂量均满足标准要求。从辐射屏蔽、放射性工作场所分区、人流物流控制、通风措施及辐射监测等方面,阐述了城市放射性废物库的辐射防护措施。为城市放射性废物库的辐射环境影响分析与辐射防护提供借鉴。The urban radwaste repository is an important public welfare environmental protection facility to ensure the safe storage of radioactive waste used in nuclear technology.In order to estimate the radiation environmental impact of urban radwaste repository reasonably and assess the exposure dose to occupational staff and the public,this paper took a new-built urban radwaste repository in a province as an example to calculate the radiation environmental impact.The results showed that the maximum annual effective dose of occupational staff and the public met the standard requirements.The radiation protection measures for urban radwaste repository were expounded from the aspects of radiation shielding,radioactive workplace zoning,people flow and logistics control,ventilation measures and radiation monitoring.It provided reference for the analysis of radiation environmental impact and radio protection of urban radwaste repository.
