Department of Energy's electronic database of worker health studies

The Comprehensive Epidemiologic Data Resource (CEDR) is the Department of Energy's (DOE) electronic database comprised of health studies of DOE contract workers and environmental studies of areas surrounding DOE facilities. CEDR provides independent researchers and the public with access to de-identified data collected since the Department's early production years. CEDR's holdings include more than 76 studies of over 1 million workers and residents living near 31 DOE sites. Access to these data is at no cost to the user. Most of CEDR's holdings are derived from epidemiologic studies of DOE workers at many large nuclear weapons plants, such as Hanford, Los Alamos, Oak Ridge, Savannah River Site, and Rocky Flats. These studies primarily use death certificate information to identify excess deaths and patterns of disease among workers to determine what factors contribute to the risk of developing cancer and other illnesses. In addition, many of these studies have radiation exposure measurements on individual workers. Other CEDR collections include historical dose reconstruction studies of past offsite radiologic and chemical exposures around the nuclear weapons facilities. The CEDR holdings also contain studies of historical interest, such as mortality studies of Japanese atomic bomb survivors and female radium dial painters; CEDR's bibliographic information includes more than 1,250 citations. CEDR is supported by the Oak Ridge Institute for Science and Education (ORISE) in Tennessee. CEDR is a national user facility, and the largest web-accessible, public-use collection of radiation exposure and health effects data in the United States.
