Abstract

The effect of the different ratios of bismuthon Nitrile Butadiene Rubber (NBR)/nano silica composite as shielding materials are studied in this study. And the study was carried on for gamma ray photon energies (0.3, 0.6, 1.25, 3 and 7) MeV obtained by (131Ir, 60Co and 137Cs) radioactive sources by using MCNP5, WINXCOM and Matlab. The numerical simulation results showed that, the shielding properties (Linear and mass attenuation coefficients, Transmission factors, Half value layer and radiation protection efficiency) of the composite materials increase with increase in the bismuth ratio and decreases with increase in energy. Also the results show that, Half-value layer (HVL) decrease with increase in the Bismuth ratio and increase with increase in gamma photon energy. It is found that the optimum concentration of Bismuth is 60%. The results confirm that rubber composites loaded with bismuth can act as an excellent gamma radiation shielding materials.
