超细离子的活性尺寸分布的测定是特别感兴趣的，由于它们对Po-218的运动和沉积的影响。这些超细离子是辐解的结果，它们的形成速率是氡浓度的函数，与Po-218的反冲路径相关的能量，以及H2O蒸气和痕量气体如SO2的存在。一个联合系列的实验，利用迁移率分析仪，单独的单屏幕的方法，和堆叠屏幕的方法进行检查的活性尺寸分布的超细模式。本文讨论了从迁移率分析仪获得的结果。
The determination of the activity size distribution of the ultrafine ions is of particular interest due to their influence on the movement and deposition of Po-218. These ultrafine ions are the result of radiolysis and their rate of formation is a function of radon concentration, the energy associated with the recoil path of Po-218, and the presence of H2O vapor and trace gases such as SO2. A joint series of experiments utilizing a mobility analyzer, the separate single screen method, and the stacked screen method were conducted to examine the activity size distribution of the ultrafine mode. The results obtained from the mobility analyzer are discussed in this paper.
