Iron is an excellent shielding material against high energy hadrons and leptons because of its high density, large inelastic inretaction cross section, low production of secomdary particles relative to heavier elements; and its moderate price. The highest contribution to the total dose equivalent behind an iron shield of proton accelerator is due to neutrons. By inelasticscattering iron effectively reduces neutron energies down to 1 MeV. Therefore iron shield (with or withoutadditional concrete) are is use around experiments at proton accelerators; sometimes magnets of an experiment have an additional shielding purpose.
This study, we investigated the shielding properties of iron shiled and iron added to concrete shield in form of particle alloy for 1000 MeV proton accelerators by means of the FLUKA Monte Carlo codes. We simulated the details of attenuation radiation forom proton bombardment of a copper target and also their subsequent transport in surrounding thick shielding.
