Entering and leaving the radiation room.

(1) Upon first entering the radiation room of a panoramic or beam-type 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.
(2) Before exiting from and locking the door to the radiation room of a panoramic or beam-type irradiator prior to a planned irradiation, the irradiator operator shall:
(a) Visually inspect the entire radiation room to verify that no one else is in it; and
(b) 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.
(3) 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 under WAC 246-236-029(2) is operating with backup power.
