Centrifugal extraction of highly enriched 123Te for the production of 123I at a cyclotron

The centrifugal enrichment of gram quantities of 99.9% 123Te by a non-steady-state separation method is described. The resulting highly enriched 123Te can be used for the production of the medical radionuclide 123I on a small cyclotron (E<20 MeV). Results indicate that the non-steady-state separation can be effectively used for the enrichment of isotopes of other elements.
