【摘要】 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和总氚(氚水和有机氚)的浓度。根据72个高于本底水平的尿中氚水和总氚浓度分析结果比较,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)%。更多还原

【Abstract】 Tritium water in urine is determinated by distillation and liquid scintillation method and the total tritium(tritium oxide and organic tritium) in urine is determinated by oxidation distillation and liquid scintillation method. Tritium water and total tritium in 72 samples of urine in which tritium concentrations is higher than radioactive backgroud of the workers in the course of the facility decommissioning in 1999 are determinated at the same time. Trtium oxide and organic tritium concentrations are compared, so the value (5.4±3.7)% of the ratioes of organic tritium concentrations to tritium oxide) is obtained.更多还原
