Thermal neutron irradiation of STACo(NH/sub 3/)/sub 5/Br!/sup 2+/ salls, producing Br/sup 80m/ and Br/sup 82/, was studied with the salts in solid and aqueous solution phases and as absorbed on a cation exchange resin, which was subsequentiy used as a meaas of separation. The fraction of radiobromine retained as ligand was determined by adding the sample to the resin and eluting the anionic bromine, then removing the ligand bromine by digesting at higher temperatures. The fraction of freed radiobromine in all oases exceeded 80%, and the order of increasing free fraction in the phases was solid, resin, solution. In the case of the salts absorbed on the resin, a considerable fraction of radiobromine was retained on the resin, which no amount of severe treatment could remove; this radiobromine is presumed to be organically combined with the resin.
