所介绍的确定空气中短寿命氡子体的单个活度的方法是基于对过滤器上收集的采样空气同时进行α和β计数。通过指数之和分解总α和总β强度的测量曲线，并评估后代的个体活性。此外，计算机模拟进行了补充气溶胶测量描述的物理过程中的氡子体在空气中的实验，并验证该方法的适用性。
The introduced method to determine the individual activities of the short-lived radon daughters in air is based on simultaneous alpha- and beta-counting of the sampled air collected on a filter. The measured curves of gross-alpha and gross-beta intensities were decomposed by sum of exponentials and the individual activities of the progenies were assessed. Furthermore, computer simulations were carried out supplemented with aerosol measurements to describe the physical processes of radon progenies in air during the experiments and to verify the suitability of the method.
