How frequently must dosimeters be calibrated?

The calibration of dosimeters is essential for ensuring the accuracy and reliability of radiation exposure measurements. Calibrating dosimeters every year aligns with recommended practices and regulatory requirements, which state that dosimeters should undergo calibration annually to maintain their precision in measuring radiation doses. This frequency allows for the detection of any drift in the dosimeter's sensitivity or performance due to various factors, including environmental conditions and the wear and tear of the device. An annual calibration schedule provides a balance between practical operational needs and the necessity of accurate radiation monitoring, helping ensure that individuals working with or around radiation are properly protected and can trust the readings from their dosimeters.
