Radionuclide source-based fluence and dose standards

Characterisation and calibration of neutron detecting devices

NPL hosts world-leading facilities for measuring the neutron emission rate from radionuclide sources and for performing fluence and dose equivalent calibrations with monoenergetic neutrons, thermal neutrons, and broad energy range neutrons from radionuclide sources or a simulated workplace field.

Services include the characterisation and calibration of neutron detecting devices, in particular personal and area dosemeters, the measurement of radionuclide neutron source emission rates and anisotropy, and also field measurements of neutron spectra and dose equivalent quantities.
