摘要
根据重庆市城市组团式建设特点,采用径迹法对重庆市主城建成区开展室内氡浓度调查。结果表明,各区县室内氡浓度整体水平较低,重庆市主城区室内氡浓度平均值为64.5 Bq/m3,168个采样点均小于国家标准200 Bq/m3;吸入氡及子体对人员产生的年均有效剂量均低于《住房内氡浓度控制标准》和《地下建筑氡及其子体控制标准规定》中规定的室内氡浓度行动水平。
Based on characteristics of delegation-style construction in Chongqing,indoor radon concentration was investigated in Chongqing urban area by track method.The results showed that level of indoor radon concentration was relatively low in different districts and countries,and average indoor radon concentration was 64.5 Bq/m3 in urban area of Chongqing.The detecting values from168 sampling sites were lower than state standard value 200 Bq/m3.The annual effective dose of radon and its progenies inhaled by inhabitants was lower than action level of radon indoor,according to ＂standard for controlling radon and its progenies in underground space＂ and ＂control standards for radon concentration in houses＂.
