WebSmall amounts of technetium can retard the corrosion of steel, although this protection can only be applied to closed systems due to technetium's radioactivity. Technetium can also be used to calibrate particle detectors. WHERE DOES TECHNETIUM-99m COME FROM? Technetium-99m is artificially produced by the neutron activation of molybdenum -99. 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.
