Abstract
Gallium-68 (Ga68) has played a relevant role for the novel studies in the nuclear medicine area. Its production have been made traditionally and initially using 68 Ge/68 Ga generators. These devices represent some flaws, namely high costs, low activity per elution and long-time waiting between elutions. In order to address these concerns, the cyclotron-based production of Ga68 has been recently investigated and has shown promising outcomes regarding the activity at the end of bombardment for both solid and liquid targets. As a globalized world in the 21st century, the use of computational tools accompanied with theoretical calculations are indispensable for having in mind all the nuclear reactions that can be generated when an isotope is undergoing an irradiation process with protons. In this work we used important CAD-based programs, Monte Carlo codes, and deterministic calculators with the objective of making a full benchmark with a previous experimental research. We also calculated the shielding requirements for this kind of isotope production facility.
