摘要
本文介绍了液闪直接测定尿氚浓度的方法。研究了采样器皿、存放方式和存放时间对测量结果的影响，同时还对直接测量法和氧化蒸馏法进行了比较。结果表明，尿氚直接测量法经济、简便，可满足核电站辐射工作人员尿氚浓度测定的要求；
This paper introduces the method for direct measurement of tritium concentration in urine using liquid scintillation.Effects of sampling containers,store patterns and storage time are studied.Meanwhile,results of two methods are compared with direct measurement method and oxidation distillation method. The results shows that direct measurement method is a economic and simple method,which can meet the need of determination of urine tritium for NPP workers.There is no significant difference compared with the data obtained by oxidation distillation method.
