摘要
本文论述了应用 β射线吸收定律测量大气中 PM10 含量的原理 ,分析了 G- M计数管的特性及测量数据的统计特征 ,提出了β射线法在测量大气中 PM10 含量的一种新的实现方法 .
The principle for measuring the content of PM 10 (Particulate Matter) in ambient air using β ray absorption law is described in this paper.The characteristic of G M counters and the statistical characteristic of data are analyzed.The new implementing method for measuring the content of PM 10 using β ray absorption law is also discussed.
