The authors conducted a nested case-control study of the association between lung cancer mortality and cumulative internal lung doses among a cohort of workers employed at the Rocky Flats Plant in Colorado from 1951 to 1989. Cases (n = 180) were individually matched with controls (n = 720) on age, sex, and birth year. Annual doses to the lung from plutonium, americium, and uranium isotopes were...

We present a comparative analysis of patterns of exposure to job stressors and stress-related workers' compensation (WC) claims to provide an evaluation of the adequacy of claims-driven policy and practice.
