Abstract:
The depth-dose distributions of 10 MeV electron beams used for food irradiation and sterilization purposes at Research and Development Center for Radiation Technology, HCMC, Vietnam are measured and the results are well re-produced by the MCNP simulations. We extend the simulations to predict the dose depth distribution for 10 MeV electron beams with the energy profiles of a model Laser Wake Field accelerator (LWFA). The dosimetry and simulation results show that the maximum dose of the depth-dose curve inside the product are 1.4 times surface dose with an area density limit of 8.6 g/cm2 for two-sided irradiation with nearly mono-energetic beams from linear accelerator and the corresponding parameters for LWFA are 1.2 times surface dose and 13.0 g/cm2, respectively.
