摘要

在测量天然水中氚的含量时，现阶段所用的闪烁液主要有两种，即二氧六环体系的闪烁液和乳化剂-甲苯（二甲苯）体系的闪烁液。乳化剂-甲苯体系的闪烁液与二氧六环系统的闪烁液比较，具有容水量高

[1]

、效率高、化学发光可以在短时间内减到本底水平的优点。用它作闪烁液，在测量天然水中的氚时，能提高测量灵敏度。

Abstract

Since the concentration of tritium is very low in natural water

the emulsion counting method was applied to increase the water capacity in scintillation solution. Thus its sensitivity can be improved. In order to select the optimal formula of Triton X-114 emulsifier-scintillator or water ratio

equi-merit value line was plotted on equilateral triangle phase diagram to determine the high merit value region. Effect of temperature on equi-merit value curve was observed. Two kinds of emulsifier

Triton X-114 and Triton X-100

were compared under different temperatures.
