摘要
Abstract
The size distribution of natural radioactive aerosols is a very important factor for evaluating the exposure dose contributed by radon. In order to measure the size distribution, a cascade impactor was employed for sampling in an underground building. The results of 4-time measurements at 58 places show that the sizes of natural radioactive aerosols are lognormal distribution, and the AMAD is between 0. 087 and 0. 427 μm with an average of 0. 194 μm. The AMADs ranging from 0. 1 to 0. 3 μm cover 85% of all data.关键词
