Calibration and maintenance of equipment is the responsibility of

• A. Nuclear Medicine Physician
• B. Health Physicist
• C. NM Technologist
• D. Radiation Safety Officer

Answer: (B)

Calibration and maintenance of equipment are handled by the health physicist. This role focuses on radiation instrumentation, quality assurance programs, and regulatory compliance, conducting acceptance testing and regular calibration of devices such as dose calibrators and gamma cameras, performing constancy and linearity checks, coordinating service with vendors, and maintaining QA records to ensure accurate measurements and safe operation. The nuclear medicine physician concentrates on patient care and interpretation, while the technologist carries out daily QC checks but does not oversee full calibration and maintenance. The Radiation Safety Officer oversees the overall safety program but relies on qualified specialists for the hands-on calibration work.
