The research and development (R&D) on the production of $$^{99}$$Mo/$$^{99m}$$Tc by (n,$$gamma$$) method has been carried out in the Neutron Irradiation and Testing Reactor Center. The $$^{99}$$Mo production by (n,$$gamma$$) reaction is a simple and easy method, and it also is advantageous from viewpoints of nuclear proliferation resistance and waste management. However, it is difficult to produce the $$^{99m}$$Tc solution with high radioactive concentration because the specific radioactivity of $$^{99}$$Mo by this method is extremely low. Up to now, various Mo absorbents such as Polyzirconium Compound (PZC) and Polytitanium Compound (PTC) have been developed with high Mo adsorption efficiency. It is necessary for utilization to the generator of these absorbents to evaluate the effect of elements containing these absorbents and to assure the quality of $$^{99m}$$Tc solution. In this report, the status of R&D of the Mo adsorbents was investigated. The alumina as Mo adsorbent, which uses in medical $$^{99}$$Mo/$$^{99m}$$Tc generator, was focused and Mo adsorption/desorption properties of three kinds of alumina was evaluated by different properties such as crystal structure and specific surface.
