摘　　要：文章介绍了对我国南方某铀矿山退役分矿环境放射性现状的调查与研究。结果表明:在所有监测项目中,完全退役的1号分矿治理完全达标;而属于政策性停产的2号分矿,某些监测点空气中氡浓度、γ辐射和水体放射性水平均超过国家限值。此外,两个分矿土壤中天然放射性核素的含量都比对照点高。This paper introduced the status of radiation environment of decommisioned submines of a uranium mine in southern China. And the results showed that in minitoring projects, the treatment effects of No. 1 decommisomed submine fully meet the governmental requirements; while, the concentration of radon in the air, radionuclide content of the water and radiation in the No. 2 submine which was cutoff by policy are over the national limitation. Besides, concerntration of radionuclide in soil at both submines is higher than the reference spot.
