THE DEVELOPMENT AND IMPLEMENT OF MEASURING PM10 CONTENT IN AMBIENT AIR USING β-RAY ABSORPTION LAW
β射线自动监测大气中PM10含量的设计方案

The principle for measuring the content of PM10 (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 PM10 using β-ray absorption law is also discussed.
