WebTechnetium can be made in one of three ways each only slightly different from the other. The first way, used by the discoverers Emilio Segre and Carlo Perrier, is taking molybdenum 98 and bombarding it with deuterons (consist of one proton and one neutron) which had been accelerated in a cyclotron. WebAbstract Introduction: Technetium-99m is the most important radioisotope used in nuclear medicine. Its routine application is ensured by introduction of 99Mo/99mTc generators.
