Abstract
A medical survey was conducted with workers exposed to uranium (7440611) and yellowcake at the Cotter Uranium Mill (SIC-1094), in Canon City, Colorado, on November 12 to 14, December 15 to 17, 1980, and February 17 to 19, 1981. The Oil, Chemical and Atomic Workers International Union and its Local 2-844 requested the evaluation after reviewing biological monitoring data indicating excessive exposures at the mill. The medical study revealed that excretion of beta-2-microglobulin was significantly higher in the urine of uranium workers compared with comparisons. Beta-2-microglobulin excretion was significantly correlated with years of work in the yellowcake mill area. No clear evidence of impaired glomerular function was evident in the uranium workers. The authors conclude that a health hazard from overexposure to yellowcake at the old mill of this facility existed. They recommended that although exposures have been substantially reduced since 1979, environmental monitoring procedures should be established, additional medical epidemiological studies should be conducted.
