Wanek, P M; Steinkruger, F J; Moody, D C

A method is described of producing substantially pure silver-109m for use in biomedical techniques. The method comprises: loading an aqueous solution of cadmium-109 onto an ion exchange substrate consisting essentially of tin phosphate; allowing secular equilibrium to be attained; and selectively eluting silver-109m from the column with an eluent solution to produce an eluate solution which contains the silver-109m and which is sufficiently free of cadmium to permit administration to a human patient.
