为摸底成都市各市区室内氡浓度分布，采用固体核径迹探测器进行监测，对测量结果分组归类分析。结果表明成都市区居室氡浓度水平以市内两条隐伏断层为界呈现北高南低的变化规律，各季节室内222 Rn浓度变化不大，平均浓度为41 Bq/ m3与世界平均水平40 Bq/ m3相当，未超过我国推荐的标准限值。%The indoor radon concentrations were surveyed by means of solid state nuclear track detector, and the results of the measurements were classified and analyzed in this essay. The paper describes the rule of change and distribution characteristics of the indoor radon concentrations of Chengdu, which is bound in two blind faults, the northwest higher and southern lower. According to the indoor radon concentration, it also estimates the effective dose for adults and finally comes to the investigation conclusion of the indoor radon concentration.
