STUDY ON MEASUREMENT AND COMPARATIVE ANALYSIS OF TRITIUM WATER AND TOTAL TRITIUM IN URINE

Luo Ning

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.
