THE ANALYSIS OF PLUTONIUM-241 IN URINE

Technical Report ·
OSTI ID:4161831
A method was developed for the quantitative determination of plutontum- 241 in exposed personnel through urine analysis, The procedure was designed for use, when necessary, in conjunction with the Harford plutonium bio-assay technique of alpha analysis. The method is based on the recovery of plutonium from electrodeposited discs and subsequent extraction of the plutonium from 1 N hydrochloric acid into a liquid scintillator containing dibutyl phosphate. The plutonium-241 beta emission is detected in a standard liquid scintillation spectrometer. The yield for plutonium recovery using spiked samples of Pu/sup 241/ was 85 plus or minus 9%. Samples containing as little as 2.2 x 10 mu ofPu may be reliably detected. This represents3.5% of the maximum permissible dose 90 days after personnel exposure. (auth)
