As an alternative to reactor-based Mo-99/Tc-99m generator technology, many research groups have suggested the direct production of Tc-99m on highly enriched Mo-100 through accelerators. For proton-induced reaction, there is a large discrepancy in 9-26 MeV beam energy range in the data available for the production of radionuclides impurities. In this work, we studied target yield and the cross section for the production of long-lived radionuclides produced in the Mo-nat target irradiated with a proton beam of energy degraded from 26 to 19 MeV in the target. This constitutes the first step, which is a commissioning of the setup and a check of the method at the beam energy where cross sections of interest are large. The step was necessary before proceeding with more demanding measurements at lower energies. Target yield was derived using the measured activity of produced radionuclides. Total cross sections for all isotopes produced from Mo-nat(p, x) reactions are presented and compared with the previously available data, showing good agreement.
