Monte Carlo calculations with MCNPX and GEANT4 for general shielding study―Application to a proton therapy center

Abstract

Monte Carlo codes have become an essential tool for studying the radiation protection of particle accelerator facilities such as a proton therapy center The MCNPX code is well adapted for shielding study but the GEANT4 toolkit is also a suitable solution Benchmark simulations – secondary-particle production and attenuation – and shielding calculations for a proton therapy center show that both codes provide results in good agreement (author)
