Traditional measures of relative risk such as SMRs, Rate Ratios, and attributable risks or fractions, are often not meaningful or intuitive for many audiences. Using simple lifetable (SMR) and more powerful Poisson regression methods, we produced estimates of SMRs, attributable risk fraction, attributable years of potential life lost, and excess lifetime risk for both chronic disease outcomes (lung cancer, nonmalignant respiratory disease) and fatal injuries. These results provide stark summaries of the magnitude of work-related mortality among uranium miners. For example, for every year employed, miners on average lost almost 4 months of life expectancy just due to risk of subsequent work-related lung cancer. Although work-related chronic disease deaths dominated (due to radon, silica and probably other exposures), more years of life were lost on average, per individual injury death (37 yrs), than for a lung cancer death (20 yrs). In deriving meaningful statements on injury risk, it is especially important to describe consequences in terms of years of life lost due to hazards on the job as well as other epidemiological measures of risk.
