Radiation Protection Instrumentation

  • Gamma doserate probes and monitors
  • Surface contamination probes and monitors
  • Neutron monitors
  • HSE performance tests for approved dosimetry services
  • Associated radiological instruments such as activity-in-air monitors

From our specialist laboratories at Winfrith and Harwell we can also undertake all aspects of equipment repair (by fully trained technicians), stock an array of common spares and technical manuals, and can design and build bespoke calibration systems to meet your specific needs.

RPI Services | Full Calibration Pricelist

The following calibration prices are valid until 31st December 2020 (E&OE).

Not all instruments are listed here please use the Contact Us link and let us know your precise requirements.

Discounts may be available for bulk calibrations.

All other calibrations are covered by Nuvia’s ISO9001:2000 registration.

Terms & Conditions

  • All laboratory activities at Harwell and Piddlehinton are accredited to ISO9001:2000.
  • The calibration of dose/doserate meters, contamination monitors, and the performance testing of HSE approved dosimetry services are accredited by UKAS.
  • An integrated dose check on doserate meters that support an ‘integrate’ facility will cost an additional £52.00 if required.
  • Integration tests that require an integration time greater than 15 minutes will be priced individually.
  • Neutron Counters are calibrated at the Harwell Neutron Calibration laboratory. The laboratory is accredited to ISO9001 and uses sources that are fully traceable to national standards.
  • Dose/doserate instruments will normally be calibrated using 137Cs and 241Am sources unless otherwise requested.
  • Alpha contamination monitors will normally be calibrated using 241Am and 234U sources unless otherwise requested.
  • Beta contamination monitors will normally be calibrated using 36Cl and 14C sources unless otherwise requested.
  • Alpha/beta contamination monitors will normally be calibrated using 36Cl and 241Am sources unless otherwise requested.
  • Where possible, the instruments will be adjusted to read correctly during the calibration.
  • The normal turn round time will be two weeks or less, from receipt of instruments at the laboratory.
  • A premium increase of 50% will be made to the calibration price if same day or next day calibration is required.
  • Polar response checks using Am-241 will cost £52.00 for each polar measurement.
  • The customer may request additional measurements that lie outside the routine procedures used by the laboratory. If the laboratory can undertake the measurements they will cost an additional £52.00 each.
  • An instrument that fails calibration will have a handling charge applied to it. The handling charge will be fifty per cent of the basic calibration price.
  • A repair service is available for instruments that fail calibration. No repairs are undertaken without the permission of the customer. The handling charge will not be applied if the instrument is repaired and calibrated by RPI Services.
  • Discount prices cannot apply when polar response checks are required.
  • The prices are exclusive of VAT and post and packaging.
  • Calibrations are done per probe or detector. If an instrument or ratemeter is used to drive more than one probe or detector the calibration price will be multiplied by the number of probes or detectors.
  • Nuvia Limited is a company registered in England and Wales with company number 2063786 and VAT number 446479317.

RPI Service | Schedule of Accreditations

In November 1990 we achieved UKAS (then NAMAS) accreditation for our gamma calibration facility at Winfrith.

Our accreditation was the first within the UK, and has since been extended to include performance testing of dosimetry services and surface contamination instrumentation.
