The Institute for Nuclear Research and Nuclear Energy at the Bulgarian Academy of Sciences is building an accelerator laboratory to operate a TR-24 cyclotron. Thus, a preliminary radiation shielding analysis of the accelerator bunker is required. For this purpose Monte-Carlo simulations have been performed and dosimetric (Dose equivalent) quantities have been estimated in two model geometries - simplified spherical geometry and full-scale bunker, respectively during operation and after the end of the cyclotron life. Our current efforts are directed to the production of 18 F thus in all the conducted simulations a water target enriched with 18 O is considered. NiGa 3 as a target for production of 68 Ge has also been simulated and a comparison of the radiation shielding characteristics of the bunker for the two targets has been made.
