Outline of Final Research Achievements

We propose a 99Mo production project via the 100Mo(n,2n)99Mo reaction using fast neutrons (E>10MeV) from accelerator. Only low specific radioactive 99Mo, however, can be obtained in this method. Although labeled technetium compounds would be available by this method, a compact technetium generator is still required in medical facilities. The purpose of this study is to investigate about production of high specific radioactivity of 99Mo and 99Mo/99mTc compact generator using and the 100Mo(n,2n)99Mo reaction with nanoparticle molybdenum target. In the fast neutron reaction with nanoparticle molybdenum targets, a certain amount of 99Mo ions are expected to be recoiled out from the target and isolated.
