Rhodotron type electron accelerator has been used for radiation processing. In this work using the MCNP code and with regard to the real geometry system radiation dose distribution in scanning and conveyor direction for electron and x-ray with energy 2 MeV calculated and compared with experimental results. The performances of the industrial electron beams processing, with 5 and 10 MeV energies, investigated by measuring two- dimensional dose distribution in electron beam profile. In addition, the mentioned measurements are also performed for x-ray (Bremsstrahlung) beam that were converted by interaction of electron with a high power x-ray target. The obtained results clearly show that the electron beam emerging out from scanning horn has a good uniformity along the electron beam profile. As well, results of the measurements show good agreement with MCNP code.
