One consisted in estimating neutron and proton fluxes with MCNPX and using them as inputs in the activation code ACAB. Induced activity in Havar foils was estimated by two procedures. The main purpose of this study is to assess induced activity radiological risk derived from the Havar foils activation. The F target has two thin circular foils composed of a metal alloy (Havar), that are highly activated by the proton beam and secondary neutrons. The cyclotron is dedicated mainly to F production. The PET cyclotron at the Centre of Molecular Imaging of the Universidad de Malaga (CIMES) is a 16.5 MeV GE PETtrace cyclotron working at dual beam (40 μA beam).
