Monte Carlo studies for the radiation shielding in the bunker of the electron beam accelerator using PHITS

摘要

Particle and Heavy Ion Transport Code System (PHITS) is a Monte Carlo simulation program used for transport and collision of nearly all particles over wide energy range. One of its useful features for accelerator facility design is the calculation of dose distribution. This paper describes how the geometry of the bunker for low electron beam accelerator in Nuklear Malaysia (NM) was modelled and used to calculate the equivalent dose caused by the radiation for specific region in the bunker by using PHITS. The dose distribution and energy deposition were obtained. Finally, the simulation results are compared to the measured value from the dose measurement testing inside the bunker facility and found both results are in a good agreement.
