Abstract
The cancer and mortality risks of Navajo males exposed to radon (10043922) progeny were updated in a new analysis of cohort mortality data for male Navajo uranium miners (SIC-1094) from the Colorado Plateau study group. A study group of 757 male Navajo uranium miners was selected from a group of individuals who worked at least 1 month underground in a uranium mine and were examined in the Public Health Service medical surveys between 1950 and 1960. Working level months of radon progeny exposure for subjects were determined by multiplying underground working months by the working level of the mine involved. Vital status was determined through analysis of Social Security Administration, Internal Revenue Service, National Death Index, Health Care Financing Administration and Indian Health Service records. Mortality ratios were calculated and used to conduct a life table analysis. A Cox regression analysis was used to account for disease mortality risk factors. Mortality from heart, circulatory and digestive diseases were found to be elevated in the study population, as were the incidences of lung cancer, tuberculosis, pneumoconioses and other respiratory diseases. The authors conclude that increased duration of exposure to underground uranium mining is related to increased mortality risk for lung cancer, pneumoconioses and tuberculosis in Navajo miners.
