How often should a radiation survey meter be calibrated?

A radiation survey meter should be calibrated annually to ensure its accuracy and reliability in measuring radiation levels. Regular calibration is essential because the performance of the meter can drift over time due to various factors such as environmental conditions, wear and tear, or electronic component aging. By calibrating the meter on an annual basis, users can confirm that the device operates within specified tolerances, providing accurate readings that are critical for safety assessments. This frequency helps maintain the instrument's integrity and supports compliance with regulatory requirements and safety standards in environments where radiation is present.
