The source of the highest amount of occupational radiation exposure is fluoroscopy and mobile radiography. This is due to the nature of these procedures, which often require prolonged exposure times, and the necessity for operators to work in close proximity to the radiation source.

Fluoroscopy allows for real-time imaging, which means that technicians may need to be present for extended periods during a procedure. The continuous exposure to radiation while assisting doctors can lead to significant dose accumulations over time. Similarly, mobile radiography requires operators to move equipment and often perform imaging in various environments, potentially increasing their exposure compared to stationary imaging systems.

While computed tomography and nuclear medicine also contribute to occupational exposure, the time spent and the type of procedures associated with fluoroscopy make it the predominant source for healthcare workers. Traditional X-ray machines typically deliver higher doses to patients but are used less frequently in a continuous imaging capacity compared to fluoroscopy, resulting in lower occupational exposure levels for radiographers and technicians.
