目的为了监测全国辐射环境质量国控点空气中氡浓度长期变化趋势。方法采用固体核径迹法测量,对不同点位测量的氡浓度测量数据进行归一化处理,分析了湿度、气压、高~(220)Rn对测量结果的影响。结果对测量方法在标准氡实验室进行了验证,测量结果误差为7.1%。结论固体核径迹法在标准氡实验室刻度后,可用于国控点空气中氡浓度累积测量。
Purpose In order to monitor long-term changes of radon concentration in the air at the national control point of radioactive environment in China. Methods The method of solid nuclear track was used to measure the radon concentration at different sites. The data of the radon concentration were normalized, and the influence of humidity, pressure and height of (220) Rn on the measurement results was analyzed. Results The measurement method was verified in a standard radon laboratory, with an error of 7.1%. Conclusion The solid nuclear track method can be used for the cumulative measurement of radon concentration in the air at the national control point after calibrating the standard radon laboratory.
