It is based on IBA (Belgium) Cyclone 70 proton cyclotron with proton energy up to 70 MeV and beam current up to 750 uA. The proton beam is split into two halves to provide simultaneous operation of two target stations. NRC KI - IHEP develops the design of the target station to produce nuclides Sr82 and Ge68 by the 70 MeV proton beam with current up to 375uA (2.3x10¹⁵ proton/s). The present work is devoted to selection of target station materials to minimize the induced radioactivity of equipment during isotopes production. The main source of this radioactivity is a flux of secondary neutrons cre-ated from proton-nuclear interactions with target materials. The nucleon-nucleus interactions and the transport of particles in substances were simulated by package of Monte Carlo codes HADR99 and FAN15 specially adapted for this task. Time dependence of the activity of nuclides accumulated in surrounding equipment and the effective dose rate after the end of bombardment (EOB) were calculated. Several alloys were considered and aluminum alloy AMg2 was chosen as most promising base material.
