Simulation of the Gamma Absorption by Lead Bronze Alloys Using Geant4

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 common platforms for interaction radiation with matter. Therefore, this paper devoted to simulating partial absorption gamma-ray by Lead bronze alloys (Pb, Sn, Cu) different proportions using from 1.5 keV 15 MeV. accuracy simulated results total mass attenuation coefficients () photoelectric effect, Compton Scattering pair production, tenth value layers (TVL) were evaluated XCOM program. agreements good, but it depends on energy incident photon. decreased when photon increased many peaks observed. effect adding Pb was clear, as increases while TVL decreases.
