Abstract
A comparison of the simulation codes MCNPX, FLUKA and GEANT4 is described for the characterisation of the high-energy neutron field at the Tri Universities Meson Facility (TRUIMF) in Vancouver, British Columbia. Particle transport simulation codes MCNPX (version 2.6.0), FLUKA (version 2011.2.17) and GEANT4 (version 9.6) have been used to model the facility This information is further compared to the neutron spectrum calculated to be due to neutron radiation of cosmic origin at typical aircraft altitudes. As a means to explain differences between the results obtained, 4 models are compared in the MCNPX environment (BERTINI, ISABEL, CEM03 and INCL4).
