摘要

本文报告了采用乳化剂和波长转移剂组成的混合溶液作为介质，提高

P、

131

I、

Ca、

S、

C等核素契仑科夫测量效率的实验方法。混合介质对高能放射性核素的契仑科夫测量效率，可比水介质中提高40—50%；对低于契仑科夫阈值的低能放射性核素也可得到一定的测量效率。本方法稳定性好、淬灭耐受性强、制样方便、水溶性样品容量大。对混合介质中乳化剂和波长转移剂的作用机制本文也进行了探讨。

Abstract

This paper presents a method on improving Cerenkov radiation counting efficiency for

132

S and

C radionuclides by using the emulsifier and wavelength shifter mixed solution as medium. The use of this mixed-medium for Cerenkov counting of high-energy β emitters is able to increase the counting efficiency 40% to 50% as compared

the water medium

and even the low-energy β emitters which below the Cerenkov threshold can also obtain higher counting efficiency. It is found that this method shows good stability

strong resistance to chemical quencher. In addition

it is particularly advantageous to large volume of aqueous sample and more convenient for sample preparation. The action mechanism of both the emulsifier and the wavelength shifter in the mixed-medium has also been discussed.
