尿中氚水和总氚的分析测定

Study on Measurement and Comparative Analysis of Tritium Oxide and Total Tritium in Urine

用蒸馏-液闪法和氧化蒸馏-液闪法分别测量了氚污染人员尿中的氚水浓度和总氚(氚水和有机氚)浓度。根据72个高于本底水平的尿中氚水和总氚浓度分析比较,认为在氚内污染工作人员的尿中,有机氚与氚水的浓度比值为(5 4±3 7)%。

Tritium oxide in urine is determinated by distillation and liquid scintillation method and total tritium (tritium oxide and organic tritium) in urine is determinated by oxidation distillation and liquid scintillation method. Tritium oxide and total tritium in 72 samples of urine in which tritium concentrations are more than radioactive background of the workers in the course of the decommissioning in 1999 are determinated at the same time.By comparison of the concentrations of tritium oxide and organic tritium, the average value (5.4±3.7)% of the concentration ratios of organic tritium to tritium oxide is obtained .
