What is the recommended action if a radiation survey instrument reads improperly?

When a radiation survey instrument reads improperly, sending it for calibration immediately is the appropriate action because calibration ensures that the instrument is providing accurate measurements. An improperly reading instrument can lead to significant risks, including insufficient protection for personnel and incorrect assessments of radiation levels in the environment. Regular calibration is essential to maintain the reliability and accuracy of radiation detection devices, ensuring they operate within specified performance standards. This approach helps to prevent potential overexposure to radiation or misinformed decisions regarding safety protocols.

While some may consider other actions, such as reporting to a supervisor or recording readings, these steps do not address the root issue of an improperly functioning instrument. Without calibration, reliance on incorrect readings can create danger, which is why sending the instrument for calibration is prioritized.
