气溶胶中总α、总β测量方法研究及山西省气溶胶放射性水平监测分析

Abstract

Abstract: To meet the requirements for monitoring gross α/β activity in aerosol samples, experiments were conducted for optimization considering of the influence of sample storage time, ashing temperature, and ashing time on the loss of radionuclides in aerosol samples, as well as the influence of sample thickness on detection efficiency. With this optimized method, aerosol samples from Datong, Linfen, and Taiyuan of Shanxi province during 2014 and 2015 were analyzed. The results indicated that the gross α and gross β activities in aerosol samples collected from Datong and Linfen were lower than those from Taiyuan, and the gross activities in aerosol samples from all four monitoring sites were higher in the first and fourth quarter than those in the second and third quarter.

Key words: aerosol, gross α, gross β, radioactivity
