Radiation Detection Instrument Calibration
EH&S operates a radiation detection instrument repair and calibration facility that can accommodate a wide variety of equipment.
Routine calibration of radiation detection instruments is a required condition of regulatory and radioactive material licensing. All portable count rate meters (commonly referred to as GM Survey meters or “Geiger “ counters) and exposure rate meters (commonly referred to as ion chambers) require annual calibration.
EH&S maintains a dedicated facility for calibrating all types of portable radiation monitoring instruments across a wide range of radiation types and levels. Instrument calibrations are performed using ANSI N323A and radiation sources certified by the National Institute of Standards and Technology (NIST) or traceable to the NIST.
The facility also specializes in the maintenance and repair of all types of portable nuclear instrumentation, including radiation detection equipment.
EH&S provides count rate calibration and exposure rate calibration of radiation detection instruments. Please contact Radiation Safety for cost rates and more information.
Labs can access EHSA to view their survey meters, liquid scintillation counters, and gamma counters; check when they were last calibrated, and see when they are due for calibration. For a step-by-step guide, click here.
