| 摘 要： | 在可调控温度、湿度及氡浓度的南华大学氡实验室对不同的湿度条件下CR-39固体核径迹探测器测量^220Rn、^222Rn的探测效率进行了测定，分析了湿度对CR-39固体核径迹探测器测量^220Rn、^222Rn探测效率的影响．实验结果表明：相对湿度在35％-95％范围内，当湿度为50％左右时，CR-39固体核径迹探测器测^222Rn，探测效率最高，标准偏差为2．0％；相对湿度在30％-100％范围内，当湿度为75％时，CR-39固体核径迹探测器测^220Rn的探测效率最低，标准偏差达到78．4％．

| Abstract: | The experiment was completed in the Laboratory of radon university which can regulate temperature, humidity and radon concentration in radon chamber. In the experiment,we measured ^220Rn、^222Rn by CR- 39SSNTD in different humidity, and analyzed the influence of humidity for the results. The results show that the detected efficiency of ^222 Rn was biggest and the standard deviation is 2.0% when the humidity is 50% from 35% to 95%. the detected efficiency of ^220Rn reached the minimum and the standard deviation is 78.4% when the humidity is 75% from 30% to 100%. |
