Nuclear shipyard worker study (1980–1988): a large cohort exposed to low-dose-rate gamma radiation

(Jun. 2, 2005) Information from the unpublished 1991 Final Report of the Nuclear Shipyard Worker Study (NSWS). The NSWS is the world’s largest and most thorough study of health effects of low-dose– rate ionising radiation to nuclear workers.A summary of the 1991 Final Report of the Nuclear Shipyard Worker Study (NSWS), a very comprehensive study of occupational radiation exposure in the US. The NSWS compared three cohorts: a high-dose cohort of 27,872 nuclear workers, a low dose cohort of 10,348 workers, and a control cohort of 32,510 unexposed shipyard workers. The cohorts were matched by ages and job categories. Although the NSWS was designed to search for adverse effects of occupational low dose-rate gamma radiation, few risks were found. The high-dose workers demonstrated significantly lower circulatory, respiratory, and all-cause mortality than did unexposed workers. Mortality from all cancers combined was also lower in the exposed cohort. The NSWS results are compared to a study of British radiologists.
