  1. The production parameters: natural TeO\(_{2}\), 18 MeV protons moderated to 14.8 MeV with 0.2 mm Havar, the proton current of 15 μA. The activity values at the end of bombardment (EOB) and the activity values after 72 hours since the end of bombardment are presented. \(^{124}\)I is highlighted in bold
