Who is qualified to operate Equipment survey devices?

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

Answer: (C)

Operating equipment survey devices requires specialized knowledge of radiation measurement, instrumentation, and QA procedures. Medical physicists are trained in radiation physics, how survey meters respond, and how to apply calibration factors and corrections. They understand background, geometry, energy dependence, and measurement uncertainty, which is essential for accurate surveys of beam output, shielding, and room contamination. This expertise lets them perform acceptance testing, routine quality assurance, and ensure measurements are traceable to standards. While radiologists and radiographers use survey devices as part of daily operations, and radiation safety officers oversee the program, the hands-on, technically proficient operation of survey instrumentation and interpretation of results is best handled by medical physicists.
