The DOE 2010 Occupational Radiation Exposure Report analyzes occupational radiation exposures at U.S. Department of Energy (DOE) facilities during 2010. This report includes occupational radiation exposure information for all DOE employees, contractors, subcontractors, and visitors. The 101 DOE organizations submitting radiation exposure reports for 2010 have been grouped into 32 sites across the complex. This information has been analyzed and trended over time to provide a measure of DOE’s performance in protecting its workers from radiation.
