The Seventeenth Annual Report of Radiation Exposures for DOE & DOE Contractor Employees analyzes occupational radiation exposures at the U.S. Department of Energy (DOE) and its contractor employees during 1984. This report includes occupational radiation exposure information for all DOE employees and contractors that are monitored for exposure to radiation. This information has been analyzed and trends over time are presented to provide a measure of DOE’s performance in protecting its workers from radiation.
