How often must dosimeters and rate alarms be calibrated?

The correct answer is that dosimeters and rate alarms must be calibrated every 12 months. Regular calibration is essential for ensuring the accuracy and reliability of these devices, which play a critical role in monitoring radiation exposure in industrial radiography settings.

The rationale behind the annual calibration requirement is that over time, equipment can drift out of calibration due to various factors, such as environmental conditions, wear and tear, or extended use. An inaccurate dosimeter or rate alarm could give false readings, leading to either unnecessary radiation exposure or insufficient protection from radiation hazards.

By adhering to a 12-month calibration schedule, users help ensure that their personnel are accurately monitored for radiation safety, which is vital for both compliance with regulatory standards and the protection of health and safety in the workplace. This annual calibration also aligns with best practices in radiation safety management, reinforcing the importance of maintaining high standards in radiation detection and measurement.
