Fast Neutrons Shielding Properties for HAP-Fe2O3 Composite Materials
نویسندگان
چکیده
Neutron has been one of the most interesting particle since its discovery. Being an uncharged it is more difficult to shield in comparison with other radiation types. This may be due differences interaction matter. The main processes neutron a matter via (n,p) reaction and thus hydrogenous materials are generally preferred neutron. In this study shielding properties for HAP composites have investigated. done using Phy-X/PSD software.
