Description:
99m Tc is the most widely used radioisotope in diagnostic radiopharmanceuticals. However, the supply of 99 Mo, the parent nuclide of 99m Tc, in Japan depends entirely on the import from foreign countries. Thus, it is necessary to supply 99 Mo stably by the domestic production, because of the unplanned shutdown and aged state of the foreign countries' reactors for 99 Mo production. Japan Atomic Energy Agency (JAEA) has a plan to produce 99 Mo. It is necessary that increasing of target volume for supplying 99 Mo stably. Pellets as irradiation target was studied. It is difficult to produce the pellets with high density, because MoO 3 sublimes at low temperature. In this study, MoO 3 pellets were produced by two kinds of production methods and characterization of these pellets were carried out. MoO 3 pellets were produced by the cold pressing sintering (CIP) method at first. Next, MoO...
