Calibration

• Radiation detection instruments are required to be calibrated annually.
• All radiation detection instruments need to be registered with the RCO. If you purchase or transfer an instrument contact the RCO
• A member of the Radiation Control Office will contact individual labs to arrange for the instrument to be picked up for calibration and return it when the process is completed. This process takes approximately a week. If you require a loaner instrument contact the Radiation Control Office.
• Do not alter the settings inside the instrument body.
• The RCO is available to assist you with further portable survey instrument calibration or service related questions or issues that you may have at rcohelp@u.arizona.edu.
