单束γ射线透射式料位计的有效量程问题

THE EFFECTIVE RANGE OF SINGLE Y-BEAM TRANSMISSION LEVEL GAUGE

摘要: <正> γ射线料位计已广泛应用于工业过程检测。检测方式依放射源的活度分布、探测器的几何形状及二者相对布置的不同而有多种。其中最基本的方式是单点源——单点探测器方式,亦即单束γ射线透射检测方式。目前采用这种检测方式的料位计仍有相当数量。

Abstract: The problem of effective range of single γ-beam transmission level gauge is presented. A calculation was made and the effective range was determined. Some factors influencing the effective range were discussed.
