Abstract
Health risks from low lead radiation exposure of workers in a plutonium (7440075) manufacturing facility were evaluated. Data was obtained from studies of workers at the Hanford Works. The statistical methodology employed a dose effect model applied to specific subgroups of the worker cohort. Maximum likelihood estimates of death rates were calculated by varying the parameters while no assumptions were made concerning cancer mortality of the workers. The dose response showed a significant downward trend at about 10 rads. The interval between cancer induction and death was a maximum likelihood estimate of 25 years. The authors suggest that cancer risk increases with age, and conclude that the exposure rate is 2 to 3 times lower by this methodology than by linear extrapolation.
