Products & Services
NPL provides a wide range of products and services to support the UK radioactivity user community.
These cover a range of radionuclides and activity levels. If you have any enquiries regarding these services, please contact radioactivity@npl.co.uk (t: 020 8943 8700).
Radioactivity products and services
- NPL can provide advice on a range of radioactivity measurement problems.
- The radioactivity facilities available at NPL.
- The Fidelis Secondary Standard Radionuclide Calibrator comprises the NPL-designed ionisation chamber and a brand new electrometer and user interface unit from Southern Scientific.
- These comparison exercises are aimed to assess the performance of the radioactivity measurement community in the UK and, more recently, participation in the exercises has become an important aspect of UKAS accreditation in this field.
- This service covers the provision of both primary and secondary standards of a range of alpha-, beta- and/or gamma-emitting radionuclides.
- NPL provides a number of services giving traceability for measurements of radioactive gases both within the nuclear industry and for estimating doses to the general public.
- The Radioanalytical Service is aimed at the measurement of a wide range of α, β and γ emitting radionuclides in divers solid and liquid matrices over a wide range of radioactivity concentrations, and is particularly aimed at the decommissioning and remediation sectors.
- Radionuclides calibrator services, including the provision of calibration factors for NPL.
- NPL supplies a range of over twenty different radionuclides for use as chemical yield tracers and calibration of various detector systems.
Standards of radioactive surface contamination for the calibration of surface contamination monitors
NPL's primary and secondary large area proportional counters are capable of calibrating a range of alpha and beta reference sources to Class 1 and Class 2 standards.- NPL provides a performance test for dosimetry services who measure tritium-in-urine as part of their internal dose assessment procedures.
- The aim of these exercises is to assess the performance of UK hospitals' nuclear medicine departments to assay the dose administered to patients undergoing diagnostic and therapeutic treatments, via the use of a Radionuclide Calibrator.
