摘　　要：根据龙和低放固体废物近地表处置场周围自然环境条件,采用国际原子能机构推荐的处置场关闭后安全评价方法,考虑处置场关闭后风蚀作用下,处置场覆盖层被侵蚀后,周围公众在处置单元上方建房以及居住所受到的剂量。经计算,处置场关闭后风蚀作用对公众造成的最大个人有效剂量为0.568 mSv/a,满足剂量控制值1 mSv/a的要求,关键核素为^(129)I,关键照射途径为食入内照射途径,风蚀景象对公众造成的影响可以接受。Based on the environment surrounding the Longhe LILW repository,this study adopted the safety assessment method recommended by the IAEA to calculate the public doses of house building scenario and residing scenario after the repository eroded by wind.The maximum individual effective dose to the public is 0.568 msv/a,which meets the requirements of dose control value.The key nuclide is ^(129)I,and the key route is ingestion.The impact of wind erosion on the public is acceptable.
