Radiation Safety Training for Sealed Source Use

The radioactive sealed source training is required for all new users of radioactive sealed sources at UW. Sealed and plated sources consist of radioactive material that is either encased in metal or plastic (sealed sources) or radioactive material that has been plated as a thin film onto metal or plastic (plated sources).

The training consists of four modules. The first three teach radiological fundamentals, regulations and oversight, and biological effects of radiation. The fourth module focuses on the safe use of sealed sources at the University of Washington. This training focuses on exposure control, ALARA (as low as reasonably achievable) concepts, utilizing time, distance, and shielding to reduce external dose, and UW specific policies for ordering and disposing of sealed sources.

This training does not fulfill training requirements for persons who use open (unsealed) sources of radioactivity or high activity gamma irradiators. To become a Radiation Worker on a sealed source Radiation Use Authorization (RUA), contact EH&S Radiation Safety at radsaf@uw.edu to begin this process.
