本文介绍对一种大面积流气式正比计数管实验装置的技术指标的实测结果,推算其α最低测量限为1.1×10~(-6)μCi/cm~2,β最低测量限为4×10~(-6)μCi/cm~2。
In this paper, the experimental results of a large-area flow-rate proportional counter experimental device are introduced. The minimum α measurement limit is 1.1 × 10 -6 μCi / cm 2 and the minimum β measurement limit is 4 × 10 ~ (-6) μCi / cm ~ 2.
