Abstract

A new activity measurement system based on two NaI(Tl) 5 × 5 cylindrical crystals, placed at 180◦, was built at the ENEA Italian National Institute of Ionizing Radiation Metrology (INMRI) and characterized by Monte Carlo simulations in FLUKA code. It was used to determine the activity of a 64Cu source, produced at ENEA’s Frascati Neutron Generator (FNG) by irradiating an enriched 64Zn sample with a 14 MeV neutron beam. Radiochemical treatments of the activated sample were performed at the ENEA Nuclear Material characterization Laboratory and Nuclear Waste Management (NMLNWM) to separate 64Cu from the zinc target and other impurities. The radioactive solution resulting from the process was measured using the Triple-to-Double Coincidence Ratio (TDCR) technique. The comparison of 64Cu activity in the solid sample and in the radioactive solution allowed to assess the separation efficiency. This study opened interesting perspectives in the production of short-lived radionuclides for nuclear medicine applications by means of 14 MeV neutron beams. 64Cu is, in fact, an emerging theranostic radionuclide currently produced with cyclotrons, irradiating very expensive 64Ni targets. From the achieved results, a prediction on the production of 64Cu with a highbrilliance 14 MeV neutron source, under construction at ENEA, was made.
