| Abstract: | A method for determination of tritium in urine has been developed.The procedure includes oxidation of organic substances in urine by potassium persulfate,purification of the urine liquid by distillation,sampling preparation with the distillation by liquid,and the scintillation cooktail then the tritium is measured by liquid scintillation counter.The minimum detection limit of the methods is about 7.6 Bq/L for the measuring period of 11 h. |
