A continuous passive measurement of indoor and outdoor radon R222n, concentration is carried out in the nearby residential areas surrounding a high capacity gas-fired power station. The mean value for indoor measurements was 26.5 ± 1.75 Bq/m that is below the worldwide indoor mean of 40 Bq/m and for outdoor was 39.4 ± 4.04 Bq/m which is higher than the worldwide average outdoor radon concentration of 10 Bq/m. The annual estimated effective doses were found to vary from 0.54 to 1.05 mSv/y with an average value of 0.67 ± 0.04 mSv/y for indoor dose and from 0.23 to 0.57 mSv/y with an average value of 0.37 ± 0.03 mSv/y for outdoor dose with an overall mean annual effective dose of 1.03 mSv/y. Furthermore, the measured and modeled radon excess levels due to plant operation, both, show that the effect of power plant emission on atmospheric radon levels in the surrounding region is not significant.
在一座大型燃气发电厂周边的居民区，对室内和室外的氡 - 222（Rn222）浓度进行了连续被动测量。室内测量的平均值为26.5 ± 1.75 Bq/m³，低于全球室内平均值40 Bq/m³；室外测量平均值为39.4 ± 4.04 Bq/m³，高于全球室外氡平均浓度10 Bq/m³。发现年度估计有效剂量在0.54至1.05 mSv/y之间变化，室内剂量平均值为0.67 ± 0.04 mSv/y，室外剂量平均值为0.23至0.57 mSv/y，平均值为0.37 ± 0.03 mSv/y，总体年平均有效剂量为1.03 mSv/y。此外，测量和模拟的因电厂运行导致的氡过量水平均表明，电厂排放对周边地区大气氡水平的影响并不显著。
