How frequently must a survey meter be calibrated according to NRC standards?

The correct answer reflects the standards set by the Nuclear Regulatory Commission (NRC), which mandates that survey meters must be calibrated at intervals not exceeding six months. This regular calibration is crucial to ensure that the instrument functions accurately and reliably measures radiation levels. Regular calibration adjustments account for any changes in the meter’s performance, which can occur due to factors such as wear and tear, environmental conditions, or electronic drift over time.

By adhering to the six-month calibration standard, operators can maintain optimal accuracy and safety in their radiation measurements, thereby ensuring compliance with regulatory requirements and protecting both personnel and the environment from unsafe radiation exposure. Meeting this standard is an essential part of proper radiation safety protocols in various settings, including medical facilities, research laboratories, and nuclear power plants.
