All researchers working in a laboratory in which open sources of radioactive materials are used must complete initial and refresher radiation safety training. The requirement applies to all researchers in an Authorized User's lab, even those who do not use radioactive materials and are not likely to enter the radioisotope area. This applies whether or not the individual has attended previous radiation safety training sessions elsewhere. Researchers who handle sealed or plated radioactive sources only must complete initial radiation safety training for sealed source users.
