The accurate estimation of secondary particle production from thick targets by intermediate energy proton or heavy ion is very important factor to determine source term in radiation shielding design.Three well-proved Monte Carlo codes the FLUKA, MCNPX, and PHITS were reviewed benchmarking calculations for proton-induced neutrons photons have been carried out.Neutron yields Be, C, Al, Fe target 113 256 MeV protons calculated compared with Meier's experimental data.From those comparisons, property above could be observed application design.The energies 100, 150, 200 230 Fe, Cu, Pb develop term.Dependence properties neutron photon found materials thickness.In this paper, a part comparison results are presented discrepancies agreements between each code discussed various energies.
