The invention provides a method for generating a daughter isotope, the method comprising contacting an ion exchange column with parent isotope; allowing the column to equilibrate between the parent and daughter isotopes; eluting the daughter isotope from the column; and repeating the equilibration and elution steps. Also provided is a system for repeatedly generating isotopes from the same support column over time with a single loading of parent isotope, the system comprising a radiation-resistant sorbent column; a parent isotope permanently contained within the column; and a fluid to elute daughter isotope from the column.
