WebTechnetium metal looks like platinum but is usually obtained as a gray powder. It crystallizes in the hexagonal close-packed structure and is a superconductor below 11.2 K. Except for technetium-99, technetium-97, and technetium-98 (4,200,000-year half-life), technetium isotopes are short-lived. WebTechnetium-99m generators. Technetium-99m is a radioactive tracer that is used in twenty million medical diagnostic procedures per year. At least 31 radiopharmaceuticals based on Tc-99m are used for imaging and studying organs such as the brain, heart muscle, thyroid, lungs, liver, gallbladder and kidneys, as well as the skeleton and blood and ...
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. Web1 jan. 2011 · The reference process uses the neutron capture reaction of natural or enriched molybdenum oxide via the reaction 98Mo (n,γ)99Mo. The irradiated molybdenum is dissolved in an alkaline solution, whereby the molybdenum, dissolved as the molybdate anion, is loaded on a proprietary ion exchange material in the chromatographic generator.
