摘　　要：目的选择我国某城市四个行政区域中的8家幼儿园,初步测量幼儿园室内氡水平。方法采用累积测量方法,在幼儿园不同活动场所布放CR-39固体核径迹探测器,布放周期为3~4个月。结果幼儿园86个测量点室内氡浓度均值为(60±34)Bq/m^3,范围为16~196 Bq/m^3。结论本次调查中8家幼儿园室内氡浓度符合相应国家标准要求。Objective To investigate the radon level of kindergartens by selecting eight kindergartens from four districts in a city of China. Methods The indoor radon concentrations of kindergartens were measured by using CR - 39 solid state nuclear track detectors, which is a eumulative measurement method. Results The 86 measurement points show that the average indoor radon concentration of the eight kindergartens is （60 ± 34） Bq/m^3, ranging from 16 Bq/m^3 to 196 Bq/m^3. Conclusion The radon concentration of the eight kindergartens meets the corresponding national standard.
