【摘要】 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²²⁰Rn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。更多还原

【Abstract】 Objective To monitor the long-term trend of the concentration of radon in the air of the national radiation environment quality control point.MethodsSolid state nuclear track method was used in measurement,Radon concentration measurement data on different point position measurement are normalized.The influence of humidity,air pressure,high of ²²⁰Rn measurement results were analyzed.Results The measurement method was tested in standard radon laboratory,and the error of measurement results was 7.1%.Conclusion Solid state nuclear track method in the standard radon laboratory scale can be used in measurement of radon concentration in the air accumulation point.更多还原
