Industrial Systems.
Some industrial X-ray systems, such as the cabinet X-ray systems used for airport
security, are completely enclosed in an interlocked and shielded cabinet. Larger systems
such as medical X-ray units are enclosed in a shielded room to which access is
restricted. Shielding for X-ray rooms is conservatively designed to handle the expected
workload conditions. Radiological control technicians (RCTs) periodically verify that
the shielding integrity has not deteriorated.
X-Ray Device Control Office (or facility-specific equivalent) personnel develop
recommendations for shielding based on the following information:
1.
Shielding the primary X-ray beam and
2.
Shielding the areas not in the line of the primary beam from leakage and scattered
