Geant4 code for simulation attenuation of gamma rays through scintillation detectors

Geant4-based Monte Carlo simulations have been carried out for studying mass attenuation for different types of scintillation detectors at different photon energies. The simulations showed that the calculated mass attenuation values are close to experimental values better than the other obtained theoretical data base for the same detector. The results indicate that Geant4 can be applied to estimate mass attenuation for various materials and energies. © 2013 Elsevier Ltd. All rights reserved.
