低本底α、β测量仪效率校准研究

摘要

This paper gives a sketch of the basic principle of low-background α, β-measuring instrument. It explores the relationship between the self-absorption, area and measuring efficiency. It gives out that the uncertain degree of efficiency calibration and analyses the application for the measuring of α,β-samples with efficiency.%简述了低本底α、β测量仪效率校准的基本原理,研究了自吸收和面积与探测效率的关系,评定了效率校准中的不确定度,并分析了效率在α、β样品测量中的应用.
