How often must survey meters be calibrated and have tags or labels attached?

Survey meters play a critical role in monitoring radiation levels, ensuring safety in environments where radiation is present. Regular calibration is essential to maintain the accuracy and reliability of these instruments. The frequency of calibration is determined by regulations and best practices in the field of radiation safety.

Calibration every three months is widely recognized in many guidelines and standards as a prudent interval for ensuring that survey meters provide accurate readings. This timeframe allows for regular checks that can quickly identify any drift in measurement due to factors like environmental changes or equipment wear, thereby maintaining the effectiveness of radiation protection efforts.

In addition to calibration, the requirement to have tags or labels attached may also be part of regulatory compliance, indicating that a survey meter has been calibrated on a specific date and providing a next due date for its subsequent calibration. This tagging system helps facilities keep track of their equipment maintenance and ensures adherence to safety protocols.

In conclusion, calibrating survey meters every three months reinforces both safety and compliance within radiation safety practices, making it the most appropriate choice for this question.
