Zirconium molybdate gel as a generator for technetium-99m

Abstract

A new (99m)Tc generator based on zirconium molybdate gel is described. Essentially the gel is a cation ion exchanger which permits the elution of the pertechnetate ion. The high molybdenum content of this gel its stability under self-irradiation and the absence of organic materials during preparation provide a generator concept that eliminates high processing costs active waste storage costs and stability problems in other types of generator.
