What type of sticker must be present on a survey meter used in industrial radiography?

A calibration sticker must be present on a survey meter used in industrial radiography to ensure that it accurately measures radiation levels. Calibration is the process of configuring an instrument to provide a correct output. For survey meters, regular calibration is essential to verify that the device operates within specified tolerances and provides reliable measurements. Without an up-to-date calibration sticker, users cannot be assured of the accuracy and reliability of the readings, which can lead to unsafe conditions in environments where radiation is present.

Having accurate measurements is critical in industrial radiography to protect personnel and ensure compliance with safety standards. The calibration sticker indicates that the meter has been tested and adjusted according to regulatory requirements, thereby confirming its readiness for use in potentially hazardous situations.
