3.3 Daily Inspection of the System

A daily inspection of the gamma radiography system for obvious defects is essential to ensure the
equipment is in a safe and proper operating condition. It is important that all radiographers perform or
supervise this inspection prior to the first radiographic exposure of the shift regardless of any previous
inspections that may have been performed that day. As an example, damage to a component of the
system may occur during transport of the equipment to the job-site. If damaged equipment were used
without detection, the result may be the inability to retract the source assembly into the gamma-ray
source projector and secure it.
The results of a daily inspection should be recorded and include the date, the name of the inspector and
what specific equipment was inspected. If any defective or damaged components are discovered during
the daily inspection, the component must be removed from service and identified with a status indicator
(tag, label, or tape) to prevent inadvertent use by other radiography personnel. Defective or damaged
components must be repaired or replaced before reuse in radiographic operations. The three main
components of the radiography system consisting of the radiographic gamma-ray source projector,
remote controls and source guide tubes must be inspected in addition to accessories such as lab stands,
collimators, J-tubes, magnetic lab-stands and pipe-clamping apparatus.
Radiographers must take a proactive role in preventing incidents, by performing or directly supervising a
simple, but thorough daily inspection of the radiography system. The implications that affect safety and
the importance of the daily inspection must be emphasized and understood by the entire radiography
staff.
