Silicone rubber composite reinforced by bismuth tungsten oxide as an effective gamma ray protective materials

Abstract The workers’ continual exposure to nuclear radiation makes it indispensable invent and form lightweight materials as flexible shields. So, in this article, silicone rubber SR inlaid with varying filler ratios of bismuth tungsten oxide Bi 2 (WO 4 ) 3 was produced. Mechanical properties, hardness, tensile strength, modulus, elongation at break, the SR/Bi composites were studied a function concentration irradiation dose. enhanced these properties. On other hand, augmentation dose, hardness increased mechanical properties decreased. Under accurate geometry conditions, gamma ray attenuation coefficients energies 661.66, 1173.24, 1332.5 keV. parameters, linear $$\mu$$ ? , experimental mass $${\sigma }_{exp.}$$ ? e x p . half value layer HVL results revealed that ability composite increase concentration. confirmed through their congruence theoretical calculations }_{theo.}$$ t h o Considering merits lightweight, high superior ability, appropriate resistance, produced is suitable durable shields such anti-radiation coats, gloves, shoes.
