Radon, thoron and their progeny concentration have been measured in dwellings located within a 90 km² area around a nuclear power plant using solid-state nuclear track detectors. Time-integrated measurements were carried out on a four-month cycle, making three measurements in each dwelling throughout the year. In total, 145 dwellings were selected for the study. The measured values of gas and their progeny concentrations were used to determine the equilibrium factor for radon and thoron indoors and annual inhalation dose. The average value of the equilibrium factor indoors was found to be 0.44 ± 0.23 for radon and 0.015 ± 0.010 for thoron. The annual inhalation dose for the public living around this plant was found to be 0.97 ± 0.55 mSv. Results were analysed for different seasons and different categories of dwellings for their construction type.

in，及其子代浓度已在90 km ²内的住宅中进行了测量使用固态核径迹探测器的核电站周围区域。以四个月为周期进行时间积分测量，全年对每个住所进行三次测量。总共选择了145处住宅进行研究。气体及其子代浓度的测量值用于确定室内ra和的平衡因子以及年吸入剂量。在室内，ra的平均值为0.44±0.23，为0.015±0.010。发现该植物周围居民的年吸入剂量为0.97±0.55 mSv。针对不同季节和不同类型住房的建造类型分析了结果。
