5.0 Operating Procedure I
5.2.1.1 exterior aurface of the device.
The sealed source shall be in the "off" position when measured.
5.2.1.2 The non-portable radiographic exposure i
devices which measure a minimum of four (4) inches from the sealed source storage l
position to any exterior su. face of the l
device and all storage containers for scaled sources or for radiographic exposure devices shall have no radiation level in excess of 200 milliroentgens per hour (200 mr/hr) at any exterior surface, and ten (10) milliroentgens per hcur (10 mr/hr) at one meter from any exterior surface.
The sealed source shall be in the "off" position when measured.
5.3 Daily Exposure Device Inspection for Portable & Non-Portable Sources 5.3.1 Each. Radiographer shall check his equipment 9nd its operation at least one time each day that it is used prior to performing any radiographic operations.
(a)
Portable Source - Radionics Model 192 and Technical Operations Model 660 shall have the following items checked.

7.
Proper operation of door lock.
(b)
Nonportable sources -
The following items shall be checked on the nonportable sources.
Namely, Radionics Model 50-2000 and Picker Cyclops Model 590C.

5.3.2 The radiographer shall indicate that the required inspection was performed in the Exposure Device Inspection Log.
5.3.3 If the Radiographer finds any problem with the equipment he shall report the problem to his Supervisor so that repair may be made as soon as possible.

5.4 Exposure 5.4.1 After making the radiographic set-up, and prior to making the exposur?, the Radiographer must visually check to assure that the exposure cell is clear of all other personnel, then close and lock '.he doors.
NOTE:
If any person becomes locked inside the cell, he may exit by turning the knob in either direction.
The door locking device is so constructed th at the doors'-
(]}
may be opened from the inside, even though the outside is locked.
This precaution shall be verified daily by the Radiographer.
5.4.2 Manipulate the source to exposed position by remote control either by crank or activating the console.
Keep the source in the exposed position for the required time.
5.4.3 Immediately conduct radiation survey at the exterior surface of the doors of the cell being used.
The level must be less than Smr/hr.
Should the level exceed 3 mr/hr, the exposure must be terminated (5.4.4 to 5.4.6) and th'e source position changed to lower the level outside the door.
()
5.4.4 Retract the source by crank or console to the shielded position when the exposure time has. expired.

Positively observe both the meter and gamma alarms to assure the source is in the shielded position.
i 5.4.6 Survey portable source container and guide tube of the Radionics Model 192, or Technical Operations Model 660, as applicable, to assure that the source is in the shielded position.
The radiation level should not exceed 50mr/hr at six (6) inches from any exterior surface of the device.

5.4.7 The portable exposure devices should be locked upon conclusion of radiographic operations, after the survey has determined that the source is in the safe position.
5.4.8 Survey nonportable source containers of the Radionics 60-2000 or Picker Cyclops, as applicable, to assure that the source is in the shiel'ed position.
The radiation level should not exceed 200mr/hr at any exterior surface, and ten (10) mulliroentgens per hour at one meter from any exterior surface.
