Simulation and extraction Protective properties of bismuth-based heterojunction Nanocomposites for shielding against gamma rays

Radiation shielding materials and components of shielding structures should have good mechanical properties, long-term usability and appropriate flexibility. Nano composites have good micro structural and mechanical properties in different conditions. This article examines the principles of gamma ray shielding, including the interaction of gamma rays with matter, bismuth-based hetero junction nano composites by combining specific concentrations (90, 90, 85, 80 percent) of bismuth oxide with vanadium as a protective material for effective radiation protection. Gamma pays. Discusses various methods of evaluating gamma ray shielding, including measurement techniques and computer simulations using the Geant4 Monte Carlo tool. Also, to check the performance of these nano composites, we have calculated effective parameters in gamma ray attenuation, such as mass attenuation coefficient, mean free distance, one-tenth layer and accumulation coefficient. Finally, this article provides an overview of gamma ray shielding, which is used to ensure the safety of people and equipment against radiation.
