本文介绍一种对可吸入α和β放射性气溶胶个人采样器所采集的微尘样品进行多样品α、β计数测量，并根据采样流量和采样时间直接计算出空气中的α和β活度浓度的测量装置。仪器一次可同时测量６个α样品和６个β样品，计数显示、浓度计算、结果显示与数据打印等功能由计算机及相应控制程序完成。 This article presents a multi-sample α, β count measurement of dust samples collected from respirable α and β radioactive aerosol personal samplers, and directly calculates the α and β activity concentrations in the air based on the sampling flow rate and sampling time Of the measuring device. The instrument can simultaneously measure 6 α samples and 6 β samples. The counting shows that the functions such as concentration calculation, result display and data printing are completed by the computer and the corresponding control program.
