摘  要:调查了我国南方某退役铀矿冶周边水环境的总α、总β放射性水平,给当地水环境提供科学数据。在铀矿冶附近的关键居民组周围设定位置、数量合适的具有代表性的采样点,采用国家《生活饮用水标准检验方法》检测。结果表明:地表水总α平均值为(0.061 9±0.020 1)Bq·L^(-1),总β平均值为(0.253 2±0.012 6)Bq·L^(-1);井水总α平均值为(0.145 7±0.018 3)Bq·L^(-1),总β平均值为(0.425 1±0.024 3)Bq·L^(-1);矿区地下水(钻孔)总α平均值为(1.223 5±0.073 9)Bq·L^(-1);总β为平均值为(0.847 6±0.059 2)Bq·L^(-1)。该退役铀矿冶周边地表水和井水总α、总β放射性符合国家规定的生活饮用水标准和地下水质量标准,矿区地下水的放射性核素没有横向迁移到矿区外,综合治理效果良好。Investigate a decommissioned uranium mining and milling around the water environment of total ct and total 13 radioactivity levels in southern China, to provide a scientific basis for local water resources. Around the key people near uranium mining and metallurgy group setting location, the appropriate number of representative sam- piing points, using national 〈 drinking water standard test method 〉 test. The results show that surface water total ot average is (0. 061 9 ± 0.020 1 ) Bq · L-1, total β average is (0.253 2 ± 0. 012 6) Bq · L-1 ;Well water to- tal et average is (0. 145 7±0.018 3) Bq · L-1, total β average is (0.425 1±0.024 3) Bq · L-1 ;Mining area groundwater (drilling) total et average is (1. 223 5±0. 073 9) Bq · L-1, total β average is (0. 847 6 ± 0. 059 2) Bq · L- 1. The total alpha and beta radioactivity of the surrounding surface water and well water of the decommissioned uranium mine are in accordance with the national drinking water standard and groundwater quality standard. The radionuelides of groundwater in the mine area do not migrate horizontally to the outside of the mine, and the comprehensive treatment works well.
