Which professional is typically qualified to operate equipment survey devices?

• A. radiologists
• B. medical physicists
• C. radiographers
• D. radiation safety officers

Answer: (B)

Measuring radiation levels and ensuring safety requires specialized knowledge of radiation physics, instrumentation, and quality assurance procedures. Survey devices must be calibrated, understood in terms of energy response and geometry, and used within a formal QA program to verify that shielding, rooms, and equipment meet regulatory limits. That expertise is what a medical physicist brings, making them the typical qualified person to operate these survey tools.

Radiologists are clinicians who interpret images, not primarily responsible for instrument calibration or routine safety surveys. Radiographers focus on acquiring the images themselves and usually operate under established QA protocols rather than performing the instrumentation they rely on. Radiation safety officers supervise the overall safety program and may oversee surveys, but the hands-on operation of survey devices is typically performed by a medical physicist who has the training to interpret results, perform calibrations, and ensure accurate dosimetry.
