Özet

Radiation transmittance properties of the functionally graded hybrid composite material with B4C + TiO2 at various proportions were analyzed using the Phy-x/PSD software. The parameters of mass attenuation coefficient and linear attenuation coefficient, tenth-value layer and half-value layer, mean free path, effective atomic number, exposure building factor, electron density, fast neutron removal cross-section, and effective conductivity were examined. Due to the increase in the proportion of reinforcing addition in functionally graded hybrid composite material, the tenth-value layer decreased while the linear attenuation coefficient value increased. The functionally graded hybrid composite material composite material (25% B4C + 25% TiO2) was found to have the best shielding properties against gamma rays and neutrons. Therefore, this material was considered suitable for new-generation uses for neutron and gamma shielding.
