摘　　要：目的调查分析长春市室内氡浓度水平及变化规律。方法采用累积测量方法,在长春市居民住宅内布放CR-39固体核径迹探测器,布放周期为3 m。结果长春市室内氡浓度水平范围为12~529 Bq/m³,室内氡浓度算数均数为80.64 Bq/m³,几何均数为52.05 Bq/m³。约有80%测量点室内氡浓度在100 Bq/m³范围内。结论室内氡浓度水平随着建筑年代的靠近呈上升趋势,并且春季室内氡浓度水平明显高于夏、秋、冬季。Objective To investigate the indoor radon level in Changchun.Methods The indoor radon concentrations were measured by using CR-39 solid state nuclear track detectors in Changchun,which was a cumulative measurement method and 3 months as a cycle.Results The 44 measurement points showed that the geometric mean indoor radon concentration was 52.05 Bq/m³ and the arithmetic mean was 80.64 Bq/m³,ranging from 12 Bq/m³ to 529 Bq/m³.About 80%of indoor radon concentrations were below 100 Bq/m³.Conclusion The indoor radon concentrations are higher with younger buildings,and are significantly higher in spring than in summer,winter and autumn.
