Concentrations of /sup 210/Pb and its states of equilibrium with /sup 238/U, /sup 234/U and /sup 230/Th in U miners' lungs

The concentrations of /sup 210/Pb and its states of equilibrium with /sup 238/U, /sup 234/U and /sup 230/Th in U miners' lungs obtained at autopsy are reported. The concentration of /sup 210/Pb ranged from 0.63 to 123 Bq/kg wet weight with an average of 32.7 Bq/kg. The /sup 210/Pb concentrations were almost seven times higher than the concentrations of /sup 238/U, /sup 234/U and /sup 230/Th. The radiation dose rates to U miners' lungs from /sup 210/Po alone ranged from 0.017 to 3.30 mGy/y with an average of 0.88 mGy/y. The dose rates from /sup 238/U, /sup 234/U and /sup 230/Th combined ranged from 6.8 X 10(-3) to 7.2 X 10(-1) mGy/y with an average of 2.9 X 10(-1) mGy/y. The dose rates from all alpha-emitting members of the /sup 238/U series, excluding /sup 210/Po, varied from 1.1 X 10(-2) to 2.2 mGy/y with an average of 7.5 X 10(-1) mGy/y.
