Abstract: Radiation-shielding glass is utilized in a few applications such as nuclear medicine, (PET) scans, x-rays, or treatment use. Nuclear reactors additionally require shielding from radiation types such as gamma, x-rays, and neutron emissions. Radiation-shielding glass is additionally utilized in the exploration and industry fields, for example, in cyclotron support testing of non-destructive materials, and the improvement of airport x-ray machines. Notwithstanding, radiation-shielding glass utilizes space innovation to protect both the astronauts and tools from cosmic rays. Nanoparticles have been involved recently in those applications. Several simulations using MCNP 6 have been used in this study to compare a variety of conventional and nanoparticle-doped glass, including silicate glass (containing BiO or PbO), BZBB5, and glass containing nanoparticles, including Na 2 Si 3 O 7 /Ag, Al 2 H 2 Na 2 O 13 Si 4 /HgO, and lead borate glass containing ZrO 2 to detect shielding properties for operators at different gamma energies. We investigated the percentage of transmitted photons, linear attenuation coefficient, half-value layer, and mean free path for the selected glass. Several shielding properties were not significantly different between the simulated results and the theoretical data available commercially. Based on the results, those parameters depend on the glass material due to their densities and atomic number. It has been found that 70 Bismuth(III) oxide:30 Silica has the best shield properties from gamma rays, such as a low percentage of transmitted photons, low HVL, and low MFP, which is due to its high density and atomic number.
