A key reagent of the TechneGen generator (NorthStar) is an ABEC (aqueous biphasic extraction chromatographic) column that consists of polyethylene glycol (PEG) bonded to a polystyrene-divinylbenzene co-polymer bead. The ABEC column is highly selective for the pertechnetate ion under highly alkaline conditions, while molybdenum passes through the column. This study was focused on determining whether radiolysis of an ABEC column used multiple times in a 20-Ci (Mo-99) generator could affect the recovery of technetium due to a radiolytic degradation of PEG. Irradiations were performed using a Van de Graaff generator.
