Calibration or Repair of Radiation Survey Meters

Environment, Health & Safety (EH&S) will notify you when your meter is due for calibration.

Meters can be calibrated at the EH&S Services Lab or you can send them to an off-campus vendor. The cost of EH&S calibration is typically less than what commercial vendors charge.

• Calibration on campus:
  • Ensure the meter is not contaminated. If you think your meter is contaminated, contact EH&S Radiation Safety, (858) 822-2494.
  • Drop the meter off at the EH&S Services Lab, University Center 301-B.
  • Provide an index number to be charged. The cost is $81.46.
  • Typical wait time is 3 days.
  • Loaner meters are available on a first come, first served basis. Read Loaner Radiation Survey Meters.
  • EH&S will also inspect the meter. If it needs repair in addition to calibration, EH&S will contact you.
  • Calibrated meters are returned with a sticker listing the meter's efficiency for measuring certain isotopes.
• Calibration by an off-campus vendor:
  • Ensure the meter is not contaminated. If you think your meter is contaminated, contact EH&S Radiation Safety, (858) 822-2494.
  • When you send your meter to an off-campus vendor for calibration, it will be returned with a calibration certificate.
  • Mail or fax a copy of the certificate to the EH&S Services Lab at:
    • Mail Code: 0035
    • Fax: (858) 822-5524

Meters can be repaired at the EH&S Services Lab for the cost of parts and labor, or you can send them to an off-campus vendor.
