PHE neutron facility: determination of neutron dose rates

This report (PHE-CRCE-004) gives technical details of Public Health England's neutron laboratory facility.


PHE-CRCE-004: Determination of neutron dose rates for the PHE neutron facility


Public Health England provides a calibration service for both passive and active neutron monitors using 241Am(Be) neutron sources. A252Cf neutron source is also available.

This report provides details of:

  • the design and construction of the neutron laboratory
  • the traceability of the neutron dose rates
  • derivation of the scatter correction
  • an uncertainty budget associated with the dose rates used during the calibration or irradiation
