Radiation Survey Meter Calibration

To request a survey meter calibration, or to inquire about a model not on our provided list, fill out the form below.

Our process…

Corwin Health Physics provides calibration of radiation survey meters to help facilities stay compliant with their radioactive materials licenses. Radiation survey meters used as part of a radioactive materials license are required to be calibrated on an annual basis (10CFR35.61).

Simply fill out the form, pay online, and ship us your meter. If any repairs are needed, we will request your authorization before completing them.

We will then remind you annually when your meter is due for calibration.

What’s included…

Our standard calibration includes:

  • One detector

  • Accuracy Check “as received” at all applicable ranges

  • Accuracy Check after calibration at all applicable ranges

  • Two measurement points per range

  • Repeatability

  • Check Source Rate if applicable

  • Battery test and replacement
