【摘要】：结合气溶胶总α、总β放射性监测工作的需要,就气溶胶样品的放置时间、灰化温度和灰化时间对核素损失的影响以及测量样品的厚度对探测效率的影响进行了优化实验,并用优化后的方法对山西省大同、临汾、太原三个地区2014—2015两年的气溶胶样品进行了监测分析。结果表明:大同、临汾两个点位的总α、总β放射性活度浓度要低于太原两个点位,4个监测点位的总放射性水平均呈现一、四季度高于二、三季度的特点。
[Abstract]:Combined with the needs of aerosol total 伪 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 伪 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.
