How often should survey meters be calibrated according to NRC regulations?

Survey meters should be calibrated annually according to NRC regulations to ensure their accuracy and reliability in measuring radiation levels. Regular calibration is essential for maintaining the effectiveness of these instruments in detecting and measuring radiation exposure, which is critical for both safety and compliance in nuclear medicine and related fields.

Annual calibration allows for any necessary adjustments to be made based on drift or changes in the meter's performance over time, ensuring that the measurements remain valid and consistent. Compliance with this regulatory requirement helps institutions maintain high safety standards and ensures that personnel are accurately informed about their radiation exposure.

While more frequent calibration might sound beneficial, NRC regulations specifically outline an annual review as the standard, unless specific circumstances warrant additional checks. This approach balances practicality with safety, ensuring that the survey meters provide reliable data without imposing unnecessary burdens on facilities.
