Abstract: (AIP)

The Institute for Nuclear Research and Nuclear Energy at the Bulgarian Academy of Sciences is building a cyclotron facility dedicated to production, and research and development of radiopharmaceuticals. 18F is of primary interest and the radiological characterization of the cyclotron and it’s vault with an 18O-target has shown that local shielding around the target will be useful in limiting the spatial distribution of emitted secondary particles and to decrease the activation of the vault walls. The current study shows preliminary numerical results on the optimization of local shielding around 18O-target for 18F production. For the purpose a simplified spherical geometry of the local shielding and the vault walls has been considered. Results for the production of residual nucleis in the vault walls been obtained.
