| 中文摘要: |
| 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%. |
| 英文摘要: |
| 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 222Rn 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%. |
