A RAPID METHOD FOR DETERMINING TRITIUM WATER IN URINE FOLLOWING ACUTE EXPOSURE

Technical Report ·
OSTI ID:4820898
HTO in the urine of exposed individuals was determined within minutes after receipt of samples by a detergentanthracene-scintillation counting method. The procedure consists merely of pipetting an aliquot of the sample onto detergent coated anthracene in a counting vial and counting in a liquid scintillation counter. Reproducibility, stubility, and sensitivity are adequate to give reliable results with tritium concentrations well below the maximum permis sible level of 28 mu c/l. Yellow pigments decrease the counting efficiency according to Beer's law, and must be removed if a highly accurate analysis is required. However, for most bioassay purposes a correction based on an optical density measurement will give satisfactory results. (auth)
