摘要

高能

粒子在透明介质中运动速度（

）大于光在该介质中运动的速度（

）时，会发生契仑柯夫辐射。其波长是非单一的，且有方向性。对介质而言，有一个与速度阈值相对应的能量阈值，只有在带电粒子能量大于介质的能量阈值时，契仑柯夫辐射才有可能发生。能量阈值是介质折射率（

）的函数，可由以下关系式

Abstract

The counting efficiency of Cerenkov radiation of

P in water by liquid scintillation counter is around 30%. The main advantage of this measuring method is that no chemical quenching problems occur during the counting. This simple fact makes it possible to prepare samples freely and easily. No scintillation solution was used

so that its cost might be reduced. Now it has been taken into account more often and is popularized rapidly. Some factors of affecting Cerenkov radiation counting such as volume

solvent and etc. were discussed in this paper. Quenching correction methods and wavelength shifters with their application and mechanism. —— the two mportant problems that are most concerned in this field

were also discussed.
