摘　　要：在概述氡及其子体危害的基础上,对现有的空气中氡浓度测量方法进行了比较,并对研制的主动式活性炭采样测氡系统进行了介绍,最后给出了在南京市人防工程内空气中氡浓度的测量结果,对氡致内照射剂量进行了估算。The problem caused by radon was summarized in this article. Radon detection methods were also compared, Then a new air radon sampler using activated carbon with a pump was introduced. Furthermore, the measured radon concentration of civil air-defense shelter （in Nanjing） was given, and the annual effective dose to the staff was calculated according to the results.
