Data collection, validation, and description for the Oak Ridge nuclear facilities mortality study

Coworker External Dosimetry Data for the Y-12 National Security Complex

“…From 1978 through the early 1990s, the Y-12 site delivered electronic files of worker data to the ORAU CER as a resource for the Health and Mortality Studies for DOE and its predecessor agencies (Watkins et al 1993). Files that were received on magnetic tapes contained records for more than 17,000 Y-12 workers.…”

A cohort mortality study of chemical laboratory workers at Department of Energy Nuclear Plants

“…For example, many former X-10 workers were also employed at the Y-12 or K-25 facilities. However, personal monitoring was not available to all potentially exposed workers until 1961 at Y-12 and 1975 at K-25 [Watkins et al, 1993]. In these cases, separate methods were developed for dose estimation similar to those suggested by Watson et al [1994] and Richardson et al [1999] using employment and facility histories and the monitoring results of nearby workers and time periods.…”

Methods for investigating age differences in the effects of prolonged exposures

“…Example: Workers Employed at ORNL: The cohort used to illustrate these analyses includes white males hired from 1943 and 1972 who worked at least 30 days at ORNL and who had not worked at another Department of Energy (DOE) facility prior to 1978 [Wing, 1993;Richardson, 1997]. Vital status was ascertained through 1990 primarily by using Social Security Administration records and the National Death Index; death certificates were retrieved, and underlying causes of death, and cancer contributory causes, were coded to the eighth revision of the International Classification of Diseases adapted for the United States (ICDA8) [Watkins et al, 1993]. All cancer mortality was defined as any death for which an ICDA8 code of 140-209 appeared as an underlying or contributory cause.…”
