Title Polonium-210 excreted in urine of the workers in a uranium mine.
Bibliographic information Dec. 1975, Vol.30, No.5, p.556-561. Illus. 14 ref.
Abstract Urinary excretion of Po-210 of workers in a uranium mine was studied to evaluate internal exposure to Rn-222 and its daughters. Subjects working inside the pit had significantly elevated urinary Po-210 levels (1.35pCi/day) while those of subjects working outside and of a control group were normal. Although there was no correlation between urinary Po-210 excretion and either accumulated working time underground or estimated internal Rn-222 exposure, the result suggests a possible environmental assessment procedure.
