Consideration of medical radioisotope production system using an electron linear accelerator

We are conducting research and development on medical radioactive isotopes (RI) production using an electron linear accelerator at Research Center for Electron Photon Science (ELPH), Tohoku University. In this research, we investigate on Mo-99 production based on high power electron linac using ¹⁰⁰Mo(γ, n)⁹⁹Mo reaction. The excitation function of photonuclear reactions (γ, n) of Mo-99 have been measured using the high power electron linear accelerator. The experimental results were compared with past of the experimental data and the yield of ¹⁰⁰Mo(γ, n)⁹⁹Mo reaction was estimated from the excitation function using PHITS code. High power electron linear accelerator is designed based on data of our basic research. The high power electron linac with energy of 30 MeV and output power of 40 kW will be described in this presentation. (author)
