Routine Production of Iodine-123 at the Karlsruhe Isochronous Cyclotron

Routine, twice-weekly, preparation of iodine-123 with the Karlsruhe Isochronous Cyclotron is achieved by bombardment of thin highly enriched 124TeO2 (> 96 %) targets with protons of 26 MeV incident energy. This paper describes the experimental details of the targetry and radiochemical procedures have been in routine use at Karlsruhe for production and separation of 123I for two years.
