氡子体的辐射剂量约占天然辐射剂量的一半以上，准确测量氡子体是评价环境中氡暴露剂量的关键。为了建立氡子体标准和控制商用装置的测量质量，分析不同测量方法的效率，确定哪种方法最适合于氡子体测量是非常重要的。通过理论分析和实验测量，对目前常用的几种测量方法进行了比较，并对其发展趋势进行了展望。结果表明，对于氡子体的测量，光谱分析法优于总计数法，而最小二乘法优于传统的三计数法或五计数法。在标定商用氡子体监测仪时，采用α + β谱的多周期计数和加权最小二乘计算方法是准确测量标准氡室中氡子体的最佳选择。
Radon exposure to the public contributes more than half of all the radiation doses caused by natural radiation; accurate measurement of radon progeny is quite essential for the dose evaluation of radon exposure in environment. For the purpose of establishing a radon progeny standard and controlling measurement quality of commercial devices, it is quite important to analyze the efficiency of different measurement methods and determine which would be the most appropriate for radon progeny measurements. Through theoretical analysis and experimental measurement, some commonly used measurement methods were compared in this study and the development trends of those methods were reviewed. Results show that for radon progeny measurement, the spectroscopic analysis method is better than the gross count method, while least-square calculation methods is better than traditional three-count or five-count method. Multiperiod counting of α plus β spectrum as well as using weighted least-square calculation method might be the best choice for accurate measurement on radon progeny in standard radon chamber when calibrating commercial radon progeny monitors.
