摘　　要：采用固体径迹探测器对某铀矿区附近居民室内外氡浓度进行了调查。对80户室内测点及25个室外测点的测量数据的统计结果表明,居民室内外氡浓度年均值(±单次测量标准差)分别为32.9(±12.1)及26.3(±18.0)Bqm^(-3)。室内外平衡因子分别为0.45和0.47。室内外氡子体照射所致成年人平均年有效剂量分别为1.02及0.32 mSv。Indoor and outdoor radon concentrations of dwellings near a uranium mine havebeen measured using solid track detector.The results of statistical data on 80 indoor mea-surements and 25 outdoor measurements indicate that the annual mean values of indoor andoutdoor radon concentration are 32.9±12.1 and 26.3±18.0 Bq·m^(-3),respectively.The av-erage values of the indoor and outdoor equilibrium factor are 0.45 and 0.47,respectively.The annual mean effective doses for indoor and outdoor exposure of adults to radon daugh-ters are 1.02 and 0.32 mSv,respectively.
