LAC 33:XV.1751. Entering and Leaving the Radiation Room

A. 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 its fully shielded position. The operator shall check the functioning of the survey meter with a radiation check source prior to entry. B. Before exiting from and locking the door to the radiation room of a panoramic irradiator prior to a planned irradiation, the irradiator operator shall: 1. visually inspect the entire radiation room to verify that no one else is in it; and 2. 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. C. During a power failure, the area around the pool of an underwater irradiator shall not be entered without using an operable and calibrated radiation survey meter, unless the over-the-pool monitor required by LAC 33:XV.1721.B is operating with backup power.
