通过对华东地区２１ 个铀矿区内居民居住环境大气中氡及其子体α潜能浓度的调查，结果表明：居民居室外氡浓度均值范围为６．７３—１３２．９ Ｂｑ／ｍ ３，氡子体α潜能浓度均值范围为１１．０—７８．８ｎＪ／ｍ ３。居室内的平均氡浓度均值范围为１４．５—１８５．８ Ｂｑ／ｍ ３，氡子体α潜能浓度均值范围为１３．８—１０４．２ ｎＪ／ｍ ３；对居民饮用水源的取样分析表明，铀浓度均值范围为０．１２—１．６８ μｇ／Ｌ，钍浓度均值范围为０．０２—０．４２ μｇ／Ｌ，镭－２２６ 浓度均值范围为０．９０—１２．１ ｍ Ｂｑ／Ｌ，与全国和当地的放射性天然本底水平比较接近，均属正常本底水平。
Based on the survey of α potential concentrations of radon and its progeny in the living environment of 21 uranium mines in East China, the results show that the average outdoor radon concentration range from 6.73 to 132.9 Bq / m 3, The mean body potential concentration ranged from 11.0 to 78.8 nJ / m 3. The average indoor average radon concentration ranged from 14.5 to 185.8 Bq / m 3, and the average radon potential α ranged from 13.8 to 104.2 nJ / m 3. Sampling analysis of drinking water source for residents The results showed that the mean range of uranium concentration was 0.12-1.68 μg / L, the average range of thorium concentration was 0.02-0.42 μg / L, the average range of radium-226 concentration was 0.90-12.1 m Bq / L, and the national and local radioactive natural background is relatively close, are normal background level.
