| Abstract | ||
| Shielding materials are extremely important in production or handling isotopes, nuclear reactors, accelerators, and medical centers, etc. The Monte Carlo simulation code Geant4 is one of the most important and common platforms for the simulation of the interaction of radiation with matter. Therefore, this paper is devoted to simulating the partial absorption of the gamma-ray by Lead bronze alloys (Pb, Sn, Cu) in different proportions using the Monte Carlo simulation code Geant4 from 1.5 keV to 15 MeV. The accuracy of the simulated results of the total and partial mass attenuation coefficients () for the photoelectric effect, Compton Scattering and pair production, and tenth value layers (TVL) were evaluated by using the XCOM program. The agreements were good, but it depends on the energy of the incident photon. The mass attenuation coefficients decreased when the photon energy increased and many peaks are observed. The effect of adding Pb was clear, as the increases while the TVL decreases. | ||
