Calculation of Shielding Parameters of Fast Neutrons for Some Composite Materials

Abstract

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