Abstract:

Copper-64 is a radioisotope of medical interest that could be used for positron emission tomography imaging and targeted radiotherapy of cancer. In this work, we investigated the possibility of producing the 64Cu isotope through a 65Cu(γ,n) reaction using high-intensity γ-beams produced at the Extreme Light Infrastructure-Nuclear Physics facility (ELI-NP). The specific activity for 64Cu was obtained as a function of target geometry, irradiation time, and electron beam energy, which translates into γ-beam energy. Optimized conditions for the generation of 64Cu isotopes at the ELI-NP were discussed. We estimated that an achievable saturation specific activity is of the order of 1–2 mCi/g for thin targets (radius 1–2 mm, thickness 1 cm) and for a γ-beam flux of 1011 s−1. Based on these results, the ELI-NP could provide great potential for the production of some innovative radioisotopes of medical interest in sufficient quantities suitable for nuclear medicine research.
