Upon first entering the radiation room of a panoramic irradiator after an irradiation, the irradiator operator shall use a survey meter to determine that the source has returned to the fully shielded position. The operator shall check the functioning of the survey meter with a radiation check source prior to entry.\n\nB. Before exiting from and locking the door to the radiation room of a panoramic irradiator prior to a planned irradiation, the irradiator operator shall:\n\n1. Visually inspect the entire radiation room to verify that no one else is in it; and\n\n2. Activate a control in the radiation room that permits the sources to be moved from the shielded position only if the door to the radiation room is locked within a preset time after setting the control.\n\nC. During a power failure, the area around the pool of an underwater irradiator may not be entered without using an operable and calibrated radiation survey meter unless the over-the-pool monitor required by 12VAC5-481-2760 B is operating with backup power.","path":["Title 12.
