(α、γ)分辨在测量CsI(Tl)晶体固有放射性本底中的应用

摘要

This paper described a charge comparison method with CAMAC-PC DAQ to identify the (α、γ) signals in CsI(Tl) crystal and measure the intrinsic radioactivity of CsI(Tl).The concentrations of 238U and 232Th in CsI(Tl) have been estimated.%描述了通过CAMAC-微机进行数据采集，用电荷比较法测量CsI(Tl)晶体的(α、γ)分辨性能的方法；同时利用此方法测量了CsI(Tl)晶体固有放射性含量，估算了晶体内238U和232Th的含量。
