Monte Carlo-based food irradiation simulator Academic Article uri icon


  • The Monte Carlo electron-transport simulation (MCNP-5) and computer axial tomography (CT) scan technology were used to predict the dose distribution in an irregular-shaped food product, an apple-phantom composed of paraffin wax, chloroform and methyl yellow. The Monte Carlo code used was successfully tested against the experimental data, resulting in less than 5% discrepancy between the simulation and measured data. The geometry and composition CT data of a real apple (Red Delicious) was then used to simulate the dose distribution in an apple irradiated by 1- and 5-MeV photon-beams. For the 5-MeV photon simulations, a lesser amount of energy was deposited closer to the surface (at the right-side surface) of the apple. It also shows a more uniform distribution in the forward direction. For a 1-MeV simulation, a higher energy was distributed at the right half of the apple, and there was no warming-up region as shown in the 5-MeV simulation. 2006, Blackwell Publishing.
