A new analytical method has been developed to determine99Tc in samples of aqueous radioactive waste containing high levels of60Co (103–106 Bq/l) in mixed forms (simple cationic60Co2+ and coordinated complex forms). The method consists of selective

A simple technique using a combination of cation exchange and solid phase extraction chromatographic resins has been developed for the separation of99Tc from other radionuclides present in nuclear fuel leachates. Quantification of the isolated99Tc is
