A Linear Accelerator is a sort of particle accelerator which produces a beam of charged particles for the production of industrial, research purposes and so on. An 10MeV linear accelerator was installed at Electron Beam Process Demonstration Research Facility, ARTI (Advanced Radiation Technology Institute, KAERI). The linear accelerator supports the technology transfer and commercialization of electron beam process technology through the development of electron beam process for large products and pilot-scale empirical research using the electron beam generated from the electron accelerator and the automatic irradiation system. The 10MeV electron accelerator supports electron beam irradiation, continuous production process design and optimization for large products (up to 10m). The accelerator also supports electron beam irradiation for various type samples (solid, liquid, film, fiber, and tube type products), continuous production process design, and optimization.
In order to operate such an electron accelerator facility, it is necessary to obtain a license to use a radiation generating device in accordance with the Nuclear Safety Act, the enforcement decree and enforcement regulations of the same Act. The operator of an electron accelerator facility must submit a radiation safety report as an attached document when applying for permission to use and pass the review by the regulatory agency, and the radiation safety report must include an assessment of the exposure dose when operating the accelerator.
In this study using the Monte Carlo computer code, MCNP, calculates the radiation dose rate outside the irradiation room due to the radiation generated by the accelerator of two types of source installed in the facility, and considers the operator''s working time. Then, the evaluated exposure dose was compared and analyzed with the reference value according to domestic laws and regulations.
Accordingly, we can protect workers and public people against radiation exposure near this facility. It could be also helpful for organizations looking to build similar facilities.
