Neutron produced in high-energy nuclear facilities are very penetrative and deeply through many materials. Neutron shielding slowed down the high-energy neutrons to thermal energies and absorbing them with suitable materials is an important problem. Neutron attenuation in the shielding is accomplished through elastic and inelastic scattering reactions. For shileding to be efficient, need to be achieved minimum thickness. To shield for these neutrons, concrete and are important materials.
In this study, the neutron attenuation effects through shileding materials (concrete, FeB and Fe2B) were investigated for various thicknesses of the materials. The high-energy neutrons were generated from the interaction of 50-1000 MeV proton energies and cupper target,, Neutron dose rate attenuation curves were determined by using FLUKA Monte Carlo code. The results shown that the extent of attenuation related to neutron energy depend on the density and thickness of the shiedling material.
