 note = {An externally controllable sealed isotope generator has been proposed for radiation education activities. Column
(68Ge-68Ga and 137Cs-137mBa) and solvent extraction (68Ge-68Ga)-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.},
