Descriptive characteristics of occupational exposures and medical follow-up in the cohort of workers of the Siberian Group of Chemical Enterprises in Seversk, Russia.

Purpose: To date, only a few studies have examined long-term health risks of exposures in the uranium processing industry and reported contradictory results, necessitating further research in this area. This is the first description of a cohort of ∼65,000 uranium processing workers (20.6% women) of the Siberian Group of Chemical Enterprises (SGCE) in Seversk, Russia, first employed during 1950-2010.
