The Comprehensive Epidemiologic Data Resource (CEDR) is a Department of Energy (DOE) public-use repository of data from occupational and environmental health studies of workers at DOE facilities and nearby community residents. DOE is the federal agency responsible for the development, testing, and production of nuclear weapons. Because this work involves exposures to ionizing radiation and other potentially hazardous materials, DOE established an epidemiologic program in the 1960's to monitor the health of its workforce. Later, an environmental dose reconstruction program was initiated to study the potential health risks due to releases that traveled off-site to communities near DOE facilities.

Data collected during DOE epidemiologic studies are available through CEDR. In 1990, the Department of Health and Human Services assumed responsibility for many aspects of the epidemiology programs and provides CEDR data from these studies as well. CEDR staff organize the electronic documentation files essential for the use and understanding of the data.

CEDR is a unique and unparalleled repository of data, providing access to information critical to understanding radiation health effects. The sharing of these research data encourages open and independent scientific inquiry among researchers, public health officials, policymakers, community groups, and other interested individuals.
