Abstract: (1889 Views)
In this research, the protective properties against gamma rays of bismuth boro-tellurite glass compounds [(TeO2)0.7–(B2O3)0.3](1-x)–(Bi2O3)x (where x equals (0.05, 0.10, 0.15, 0.25, and 0.3 mole fraction) is investigated using the Monte Carlo simulation tool Geant4 in the range of 0.015 to 15 MeV. In this study, the quantities related to photon attenuation such as: linear attenuation coefficient (𝜇L), mass attenuation coefficient (𝜇m), one-tenth-value layer (TVL), half-value layer (HVL), effective atomic number (Zeff), effective electron density (Neff) ), the total atomic cross section (σa), the total electronic cross section (σe) and the mean free path (MFP) Also, the spectrum of secondary particles created in these compounds is shown according to their type and energy for different levels of incident gamma energy. To validate the simulation results, the mass attenuation coefficient values calculated from Geant4 were compared with the Phy-X results, which show that they are in good agreement with each other. The agreement between the data shows that the Geant4 tool is a good method to check the properties of gamma ray shielding. The obtained results show that with the increase of the bismuth element in the composition of the glass, its protective property also increases and the quantity values are at the optimal level that these glasses can be used as a substitute for lead glasses (due to the toxicity of lead) used in lower energies.
