^99mTc is used for many of radiopharmaceuticals. ⁹⁹Mo is parent nuclide of ^99mTc. In order to apply (n, γ)⁹⁹Mo to the ⁹⁹Mo/^99mTc generator, improving the performance of alumina is necessary. In this study, the Mo adsorption and ^99mTc elution properties of three kinds of alumina specimens were examined using MoO₃ irradiated in KUR.
