本文提出了一种测定氡-222污染大气中RaA、RaB和RaC浓度的新方法。该方法采用α光谱法测量在两个采样后时间存在于膜过滤器样品上的RaA和RaC'的计数率。然后，可以从给出的方程计算各个空气浓度和与每个相关的统计方差。理论和实验的比较表明，改进的精度的光谱方法比以前可用的方法。
A new method is presented for determining the airborne concentrations of RaA, RaB and RaC in atmospheres contaminated with radon-222. The method employs alpha spectroscopy to measure the count rates of RaA and RaC'present on a membrane filter sample at two post-sampling times. The individual air concentrations and the statistical variances associated with each then may be calculated from the equations given. Theoretical and experimental comparisons are presented which indicate the improved accuracy of the spectroscopic method over methods previously available.
