【摘要】：結(jié)合氣溶膠總α、總β放射性監(jiān)測(cè)工作的需要,就氣溶膠樣品的放置時(shí)間、灰化溫度和灰化時(shí)間對(duì)核素?fù)p失的影響以及測(cè)量樣品的厚度對(duì)探測(cè)效率的影響進(jìn)行了優(yōu)化實(shí)驗(yàn),并用優(yōu)化后的方法對(duì)山西省大同、臨汾、太原三個(gè)地區(qū)2014—2015兩年的氣溶膠樣品進(jìn)行了監(jiān)測(cè)分析。結(jié)果表明:大同、臨汾兩個(gè)點(diǎn)位的總α、總β放射性活度濃度要低于太原兩個(gè)點(diǎn)位,4個(gè)監(jiān)測(cè)點(diǎn)位的總放射性水平均呈現(xiàn)一、四季度高于二、三季度的特點(diǎn)。
[Abstract]:Combined with the needs of aerosol total 偽 and total 尾 radioactivity monitoring, the effects of aerosol sample placement time, ashing temperature and ashing time on radionuclide loss and the influence of sample thickness on detection efficiency were optimized. The aerosol samples in Datong, Linfen and Taiyuan of Shanxi Province in 2014 / 2015 were monitored and analyzed by the optimized method. The results show that the total 偽 and 尾 radioactivity concentrations of the two points in Datong and Linfen are lower than those in Taiyuan, and the total radioactivity levels of the four monitoring points are all in the first and fourth quarters, which are higher than those in the second and third quarters.
