In the medical field, diagnostic techniques are a fundamental method used to help diagnose a disease or condition. The single photon emission computed tomography (SPECT) is a diagnostic technique that covers more than 80% of all the nuclear medicine diagnostic procedures worldwide. One of the tracers used for it is 99mTc, generated by radioactive 99Mo. This radionuclide is produced irradiating uranium samples with neutrons generated in fission reactors, thus producing fission products and chemically separating molybdenum from the rest. Within this frame, Sorgentina-RF project aims to design a facility to produce 99Mo in a large-scale, cheaper and more efficient way than the methods presently adopted.
