摘要

液体闪烁谱仪一般用于测量含有

H、

C等低能

放射性核素的样品。当电子能量超过263keV时，在水中就能产生切伦科夫辐射。

粒子的最大能量为1.7MeV，是理想的切伦科夫辐射源。我们用液体闪烁谱仪进行切伦科夫计数时，为确定最佳介质体积，提高计数效率，研究了

P在几种介质中的计数效率与介质体积的关系。

Abstract

This paper discribes the effect of different kinds and volumes of medium on the counting efficiency by Cerenkov radiation with liquid scintillation spectrometer of type YS-2

which was made by our institute. The emphasis is put on the relation between the concentration of emulsifier solution and counting efficiency. We found the

P peak of counting efficiency is at the place where concentration is about 77% (efficiency is about 65%) . The experiment proves that

P counting in emulsifier solution by Cerenkov radiation has good stability both in time and temperature.
