“…HVL is a crucial parameter for comparing the shielding performance of materials since different materials attenuate radiation to different degrees. Table 4 lists the HVL for the six shielding materials, representing the material thickness that will attenuate half of the gamma rays [25]. As shown in Figure 4 a,b, the low-density materials and high energy sources have high HVL, which means that they will require more material thickness to attenuate the gamma rays completely, which is also concluded from the percentage of transmitted photons for the low-density materials and high-energy sources.…”

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 Na2Si3O7/Ag, Al2H2Na2O13Si4/HgO, and lead borate glass containing ZrO2 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.

The linear and mass attenuation coefficients of raw Rhizophora spp. wood, binderless particleboard, and Perspex were measured at gamma ray energies of 59.54, 88.0, and 356 keV. Americium-241, cadmium-109, and barium-133 point sources were used to produce gamma rays in this work. Results were compared with the theoretical values of water calculated using the XCOM program. The mass attenuation coefficients of binderless particleboard and water showed good agreement, with discrepancies of approximately 0.1, 0.6, and 0.1% at 59.54, 88.0, and 356 keV, respectively. The measurements of raw Rhizophora spp. wood and water had discrepancies of 0.7, 0.9, and 0.8% at 59.54, 88.0, and 356 keV, respectively, and those of Perspex and water had discrepancies of 0.3, 0.9, and 0.2% at the same photon energies. Moreover, Rhizophora spp. binderless particleboard was compared with water in terms of effective atomic number (Zeff), and a close match was noticed. In addition, the half-value layers of the experimental samples were measured at 59.54, 88.0, and 356 keV. The calculated values of water and the experimental results of binderless particleboard were in good agreement, indicating that binderless particleboard can be used as a phantom material in the range of photon energy 59.54–356 keV.
