Instrument Calibration

At RSCS, we calibrate survey meters and dosimeters in fields ranging from 100 µR/hr to over 10,000 R/hr using NIST-traceable Cs-137 sources.  In addition, we perform calibrations for neutron detectors using a fully characterized AmBe source.  Our contamination monitoring equipment calibrations include complementary detector efficiencies using NIST-traceable radioisotopes commonly used in industrial, medical and research applications. We are licensed to perform calibrations on instruments with fixed and loose contamination (see Contaminated Instruments Requirements below).  Additional calibration capabilities include scalers, high and low volume air samplers and lapel air samplers. 

Instrument receipt, inspection, calibration and return shipment is normally completed within 4 business days.  Expedited same day and next day service is also available upon request.  Calibration certificates are issued with each instrument, listing as-found and as-left data, with indications of any out-of-tolerance conditions.  Our custom instrument calibration tracking database logs all calibration history data and provides automatic calibration-due reminders to customers.

Services offered include:

  • Expanded calibration range: measurements from 100 µR/hr to over 10,000 R/hr
  • Standard calibrations: meters calibrated within +/- 10%, electronic dosimeters within +/- 5%
  • Customized calibrations: contamination monitors adjusted to customer specifications
  • Complementary efficiencies: 2 efficiencies per calibration
  • Detector Optimizations: High voltage Plateau and E2/B testing
  • Air sampler and lapel calibrations
  • Calibrations of instruments with fixed and loose contamination (see Contaminated Instruments Requirements below) 
  • Thorough documentation: all instrument data detailed in calibration reports
  • Easy access to calibration data: via email and web
  • Reminder letters: customer notification of upcoming calibration expirations
  • On-site calibrations and calibration source characterization.
