Comprehensive Epidemiologic Data Resource (CEDR)
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. DOE
recognizes the benefits of data sharing and supports the public's right to know
about worker and community health risks. CEDR provides independent researchers
and the public with access to de-identified data collected since the
Department's early production years. Current CEDR holdings include more than 76
studies of over 1 million workers at 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, the Oak Ridge
reservation, 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. CEDR is supported by the
Institute for Science and Education (ORISE) in Oak Ridge, Tennessee. Now a
mature system in routine operational use, CEDR's modern internet-based systems
respond to thousands of requests to its web server daily. With about 1,500
Internet sites pointing to CEDR's web site,
CEDR is a national user facility, with a large audience for data that are not

Analytic Data File Sets = 261 data files (60 studies)
Analytic data files contain the data that a researcher directly used in conducting the analyses and result in reported findings or publication in a peer-reviewed journal.
Working Data File Sets = 118 data files
Working data files are files that contain the raw or unedited data from which a researcher selected variables to form an initial analytic data file set. The data in the working data files may contain errors; as such, it is recommended that they be analyzed and results interpreted with caution.
CEDR's library of information, reports, journal articles, and data includes more than 1,250 citations. CEDR's various types of bibliographic searches allow the user to select citations or publications associated with the studies found in the CEDR library.
