For what period is radiological training valid?
General Employee Radiological Training (GERT), Radiological Worker training (RW), radioactive source training, and Material Move Request Form (MMR) training must be completed every 2 years. We have made the interpretation that the training expires at the end of the calendar month in which the previous training was received. For example, if one were trained on April 1, 1996, that persons training expired on April 30, 1998.
