摘　　要：通过对云南某伴生放射性矿企业其中一个锗矿采区放射性水平调查,主要调查内容:X-γ辐射空气吸收剂量率;废石样、原矿样(锗矿)、土壤及底泥样中天然放射性核素^(238)U、^(232)Th、^(226)Ra和^(40)k比活度;矿坑涌水及水样中的天然放射性核素U、Th、^(226)Ra和总α、总β比活度;流出物空气中氡浓度、气溶胶中γ核素活度浓度监测。了解该矿区开采和生产过程中对周围辐射环境影响现状,根据监测结果,该矿区存在放射性污染,提出了污染防治措施。By investigating the radioactivity level of a germanium mining area of an associated radioactive mining enterprise in Yunnan,the present influence of mining and production on the surrounding radiation environment was examined.The main contents of the investigation were air absorbed dose rate of X-γ radiation;the specific activities of natural radionuclides 238U,232Th,226Ra and 40K in waste rock samples,raw ore samples(germanium ore),soil and sediment samples;soil and sediment samples,the natural radionuclide activities of U,Th,226Ra and totalα,total β in gushing water and water samples from mines,and the specific activities of U,Th,226Ra and totalα,total β in water samples were determined Monitoring of Radon concentration in air andγnuclide activity in Aerosol.According to the monitoring results,the pollution prevention and control measures were put forward.
