Abstract

Abstract: An externally controllable sealed isotope generator has been proposed for radiation education activities. Column ( 68 Ge- 68 Ga and 137 Cs- 137m Ba) and solvent extraction ( 68 Ge- 68 Ga)-based isotope generators were applied as radioactive sources. These generators showed high milking efficiencies and low breakthrough after repeated uses, and are expected to promote the use of isotope generators without radioactive contamination or the emission of radioactive waste. This isotope generator provides a new concept for sealed radioisotope sources. Highlights: Developed an externally controllable sealed isotope generator. Solid-liquid and solid-solid separation generators were applied. Maintained high extraction efficiency and low breakthrough during repeated extractions.
