摘　　要：对金塔某拟建中低放固体废物近地表处置场接收处置部分废放射源的环境影响进行研究计算。根据该处置场周围环境条件,对处置场关闭后的景象进行分析。计算了处置场关闭后钻孔景象、钻孔后景象以及废放射源装口袋景象下的环境影响。计算结果表明:废放射源装口袋景象对公众造成的剂量最大,为0.35 mSv/a,小于处置场剂量控制值1 mSv/a,对环境的影响可以接受,关键核素为^(137)Cs。According to the environmental surrounding the LILW repository in Jinta,Considering the drilling scenario,after drilling scenario and bagging scenario,to calculate the environmental impact of spent radioactive source in the LILW disposal.The results show that the critical scenario is bagging scenario,the maximum dose is 0.35 mSv/a,which is less than the dose control value of 1 mSv/a,the key nuclide is Cesium -137.It shows that the LILW dispose the spent radioactive source is acceptable.
