摘要
根据塑料管内活性炭吸附空气中的钍射气２２０Ｒｎ的实验数据和高纯锗探头探测效率的空间分布规律，设计了三种空气中钍射气２２０Ｒｎ的收集器。
The data about the ability of activated charcoal absorbing thoron 220 Rn in air was dertermined through a series of experiments.Especially,the activated charcoal, loaded in the experiments, were different in section area, length, rate of flow,humidity, etc. The space distribution of counting efficiency, surveyed using the HP-Ge detector, was measured by a 226 Ra point source, so the basis for designing the activated charcoal monitor for 220 Rn in air was provided, and three kinds of monitors with different forms were designed.
