Abstract

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

摘要

报告了在尸检时获得的铀矿工人肺部中210Pb的浓度及其与238U、234U和230Th的平衡状态。210Pb的浓度范围为0.63至123贝克勒尔/千克湿重，平均为32.7贝克勒尔/千克。210Pb的浓度几乎是238U、234U和230Th浓度的七倍。仅210Po对铀矿工人肺部的辐射剂量率范围为0.017至3.30毫戈瑞/年，平均为0.88毫戈瑞/年。238U、234U和230Th的组合剂量率范围为6.8×10^(-3)至7.2×10^(-1)毫戈瑞/年，平均为2.9×10^(-1)毫戈瑞/年。238U系列中除210Po外的所有α发射体的剂量率从1.1×10^(-2)至2.2毫戈瑞/年不等，平均为7.5×10^(-1)毫戈瑞/年。
