Abstract
The thorax burden and daily urinary excretion of uranium (Y class) wer e simultaneously estimated using the techniques of whole-body counting and neutron activation analysis respectively, for a group of 23 occup ational workers in a uranium oxide plant. The results of the estimatio n showed a statistically significant (p < 0.05) linear correlation bet ween the thorax burdens and the corresponding daily urinary excretions . The values of the mean thorax burden and the mean daily uranium excr etion were employed to arrive at the pulmonary clearance fraction for the uranium deposited in the pulmonary region. The value of this fract ion (which is the ratio of uranium excreted daily in urine to that pre sent in the thorax) was found to be 1.1 x 10(-4) d-1.
