摘　　要：测量巴彦乌拉铀矿周围土壤中的放射性核素含量,并评估环境放射性及其对居民健康的潜在影响。通过采集铀矿区周边30 km范围内的43份土壤样品,利用超低本底高纯锗γ能谱仪对核素含量进行了测定,并应用ArcGIS10.8软件分析了核素分布。结果显示,铀矿区表层土壤样品中的238U,232Th,226Ra,40K,137Cs比活度平均值分别为(10.52±1.89),(23.75±4.28),(16.32±2.94),(737.82±132.86),(3.14±0.57)Bq/kg,除放射性核素40K高于我国和世界环境放射性本底水平580 Bq/kg和412 Bq/kg范围外,其余核素均在环境放射性本底水平范围内。结论表明,在巴彦乌拉铀矿区30 km范围内环境放射性水平处于正常范围,对周围居民健康风险无显著影响。Radionuclides in the soil surrounding the Bayan-Ula uranium mine were measured and environmental radioactivity and its potential effects on the residents’health were assessed.By collecting 43 soil samples within 30 km of uranium mining area,the radionuclide content was determined by ultra-low background and high purity germaniumγ-ray spectrometer,and the distribution of nuclide was analyzed by ArcGIS10.8 mapping software.The results showed that the average specific activity values of 238U,232Th,226Ra,40K and 137Cs in surface soil samples of uranium mining area are(10.52±1.89),(23.75±4.28),(16.32±2.94),(737.82±132.86)and(3.14±0.57)Bq/kg respectively.Except for the radionuclide 40K,which is higher than the background level of environmental radioactivity in China and the world of 580 Bq/kg and 412 Bq/kg,the other radionuclides are within the background level of environmental radioactivity.The conclusion shows that the level of environmental radioactivity within 30 km of Bayan-Ula uranium mine is in the normal range,and has no significant effect on the health risk of surrounding residents.
