Personnel monitoring devices should be calibrated at what interval to maintain accuracy?

Personnel monitoring devices must be calibrated annually to maintain their accuracy and reliability in measuring exposure to radiation. Regular calibration ensures that the devices continue to meet safety standards and provide valid measurements, which are crucial for monitoring radiation exposure among staff working in environments where radiation is present.

Calibration is part of quality assurance practices, ensuring that instruments measure correctly and consistently over time. By conducting this annual calibration, facilities can ensure compliance with regulatory guidelines and maintain the safety of their personnel.

Other intervals, such as monthly, every five years, or every other year, may render the monitoring devices susceptible to drift in measurements due to environmental factors, wear and tear, or technology changes, potentially leading to unreliable readings that could compromise safety and oversight.
