| Abstract | ||||
| Environmentally hazardous radiation sources can negatively affect human health. For example, tumors, cancer, a decrease in lymphocyte cell count, and severe cases of fatalities. Because of this, the present work aims to explore the radiation-protecting performances of the metal-tungstate oxides: CaWO4, SrWO4, BaWO4, and PbWO4 as a comparative study that provides effective strategy for developing sustainable and alternative shield material. The mean track length of incoming photons inside four distinct metal tungstate oxides has been determined using the Monte Carlo simulation code. Then, other significant gamma-ray shielding characteristics were computed based on the predicted track length. For all samples, attenuation coefficients are estimated by MCNP5 simulation code, which showed satisfactory agreement with the Phy-X/PSD results. It also used to figure out the half-value layer, mean free path, effective atomic number, and effective electron density. The mass attenuation coefficient and effective atomic number are energy and density dependency, have maximum values at the lowest energies and minimum values at the highest energies. The study findings imply that the atomic density and metal tungstate oxide composition of the material determine the correlation between the photon and the shield material. The results showed that the maximum mass attenuation coefficient was achieved for PbWO4 that is a superior candidate for radiation shielding applications. | ||||
