摘　　要：本文分析了新疆城市放射性废物库2012—2016年的γ剂量率、中子剂量率、表面沾污、氡浓度、土壤中放射性核素比活度以及地表水核素含量变化情况。监测结果表明:新疆城市放射性废物库库区内新库、老暂存库以及库外周围γ辐射剂量率和中子剂量率均处于乌鲁木齐市正常本底水平,表面沾污和氡浓度均未见异常,库区周围环境地表水白鸟湖总α、总β放射性浓度均低于《生活饮用水卫生标准》,土壤中γ核素均在乌鲁木齐市环境土壤天然放射性水平范围中。通过废物库的监测,对掌握新疆城市放射性废物库周边放射性水平,开展环境辐射评价提供了科学依据。In this paper,the changes ofγdose rate,neutron dose rate,surface contamination,radon concentration,radionuclide specific activity in soil and radionuclide content in surface water in Xinjiang city radioactive waste repository from 2012 to 2016 were analyzed.Monitoring results show that the repository gamma radiation dose rate and the neutron dose rate in urumqi normal background level,there were no abnormal surface contamination and the radon concentration in Xinjiang city radioactive waste vault area of the new repository,around and outside of old temporary.The radioactivity concentrations of totalαand totalβin the ambient surface water of Baiiaohu Reservoir area were lower than the Sanitary Standards for Drinking Water.Theγ-nuclides in the soil were all in the range of natural radioactivity level in the environmental soil of Urumqi.Through the monitoring of the waste depot,it provides a scientific basis for grasping the radioactivity level around the city radioactive waste depot in Xinjiang and carrying out environmental radiation assessment.
