Calculation of Shielding Parameters of Fast Neutrons for Some Composite Materials


In this paper ,Shielding parameters of fast neutrons likes removal cross section , half thickness, and mean free path were calculated for polymer composite which consisted of paraffin wax as basic material (P) with various reinforced materials [Boron )B(, Boron trioxide )B2O3(, Iron(III) oxide )Fe2O3(, Tungsten )W(, Kaolin (Clay)] with different reinforced concentration (5, 15, 25, 35, 45) % weight percentage . Results have been shown that ,with increasing the reinforced materials concentrations , removal cross section increases while half thickness and mean free path decreased.
