摘要

本文介绍用液体闪烁技术测量Na

或NaH

的一种改进方法。在一定量的蒸馏水中加入适量的Na

载体和NaOH，再加一定量的待测Na

溶液，制成供测量用的放射性浓度适中的Na

贮备液。在甲苯/Triton X-100闪烁系统(PPO4g

POPOP 0.25g

Triton X-100 165ml

加甲苯至500ml）中加入DL-

-苯乙胺，最后加入Na

贮备液，制备样品。用样品道比法测定效率。每日测量一次，在连续测量的9天中，未发现

C损失，也未发现存在化学发光，探测效率约为83%。

Abstract

In this paper an improved method for counting the radioactivity of Na

by liquid scintillation technique is reported. Na

solution was added into toluene/Triton X-100 scintillator which was mixed with CO

trapping agent

DL-

-phenylethylamine. The radioaetivity of Na

was measured for nine days with no observed radioactivity loss. The radioactivity recovery was about 96—102% and the counting efficiency was about 83%.
