title: Health effects in underground uranium miners.
abstract: The health effects associated with uranium miners have received much attention in the last 30 years. Although mortality rates are elevated for such causes as accidents and nonmalignant respiratory disease, lung cancer caused by exposure to radon decay products is the primary hazard to underground uranium miners. This review summarizes studies of eight cohorts of radium miners, and examines several pooled analyses that provide the best understanding of the radon/lung cancer relationship. The relative risk of lung cancer is linearly related to cumulative exposure to radon decay products. The excess relative risk decreases with attained age and time since exposure. An inverse exposure-rate effect exists, such that prolonged exposure at low levels of radon is more hazardous than shorter exposures to higher levels. The linear no-threshold model used in most epidemiologic studies has been attacked by some as overestimating risk at indoor radon levels. These arguments are rejected by this reviewer.
