Everyone is exposed to radiation every day and sources of radiation often surround us. Some are natural and some are man-made, but we can’t see or feel radiation’s presence.

That “CAUTION IONIZING RADIATION” yellow and black warning sign is intimidating enough to frighten anyone – as though any thought of radiation exposure is enough to us running for SCBAs, chemical suits, and bunkers.

The objective of the Department of Energy’s Radiation Protection Program (RPP) is to ensure radiation exposures to DOE workers and the public, and releases of radioactivity to the environment, are maintained below regulatory limits, and deliberate efforts are taken to further reduce exposures and releases as low as reasonably achievable.
