                   Subpart D--Operation of Irradiators
 
Sec. 36.67  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 may not be entered without using an operable and 
calibrated radiation survey meter unless the over-the-pool monitor 
required by Sec. 36.29(b) is operating with backup power.
