为掌握地浸铀矿氡析出所致辐射剂量,通过对某地浸铀矿进行环境空气中氡浓度、氡析出率调查与测量,估算了水冶车间工作人员所受年个人辐射剂量,并运用UAIR-FINE软件模拟集液池、蒸发池所致周围20 km范围内各子区的氡浓度贡献值分布、公众个人剂量分布。结果表明:井场及水冶车间室外氡浓度基本处于环境本底水平;生活区、工作场所的氡浓度以及所致工作人员的个人剂量低于国家规定的标准;所致居民点氡浓度贡献值、公众个人剂量最大值均低于国家目标限值,因此该地浸铀矿氡析出所致影响较小,并针对地浸铀矿的特点提出了合理的氡析出防护建议。

In order to master the radiation dose of radon exhalation from in-situ leaching uranium mine, the radon concentrations and radon exhalation rate in the ambient air were investigated and measured through in-situ leaching uranium. The annual personal radiation dose of hydrometallurgy workshop on staff was estimated. The distribution of radon concentration values, as well as public individual dose in each area at the range of 20 kilometers around, caused by leaching pool and evaporation pool, were simulated by utilizing UAIR-FINE. The results show...
