A survey of the 222Rn concentrations in 106 homes in the four main towns of the Central Asturias region was carried out over three years. A total of 1,014 measurements was obtained using passive radon charcoal canisters. The 222Rn concentrations fit a log-normal distribution law, with a geometric mean of 23 Bq m(-3). There is a marked difference between the 222Rn concentration for the ground inhabited floors and first floors. For the other floors, the 222Rn concentrations remain practically constant. The 222Rn concentrations are lower in summer than in winter time. The annual equivalent dose for the general public due to the inhalation of 222Rn is equal to 0.81 mSv (81 mrem).
在三年时间里，对阿斯图里亚斯中部地区四个主要城镇的106户家庭中的222Rn浓度进行了调查。使用被动式氡活性炭罐共获得了1014次测量结果。222Rn浓度符合对数正态分布规律，几何平均值为23 Bq m(-3)。地面居住层和一层的222Rn浓度存在显著差异。对于其他楼层，222Rn浓度基本保持不变。夏季的222Rn浓度低于冬季。公众因吸入222Rn所致的年等效剂量等于0.81 mSv（81 mrem）。
