TECHNETIUM Technetium is the only element below uranium that does not exist on Earth. It is a synthetic (man-made) element produced in a particle accelerator. For many years, chemists knew that an element with atomic number 43 must exist, based on an empty spot in the periodic table.

Technetium-99m Technetium-99m is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99m Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope.echnetium-99m can be readily detected in the body by medical equipment because it emits 140.5 keV gamma rays (these are about the same wavelength as emitted by conventional X-ray diagnostic equipment), and its half-life for gamma emission is six hours (meaning 94% of it decays to 99 Tc in 24 hours).

Technetium-99m Technetium-99m is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99m Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope.echnetium-99m was discovered as a product of cyclotron bombardment of molybdenum. This procedure produced molybdenum-99, a radionuclide with a longer half-life (2.75 days), which decays to Tc-99m. At present, molybdenum-99 (Mo-99) is used commercially as the easily transportable source of medically used Tc-99m.

Ultra-TechneKow This generatorprovides a closed system for the production of sterilemetastable technetium Tc-99m, which is produced bythe decay of molybdenum Mo-99. Sterile, non-pyrogenic isotonic solutions of Sodium PertechnetateTc-99m can be obtained conveniently by periodicaseptic elution of the generator.

Technetium-99m Technetium -99m is produced by bombarding molybdenum 98 Mo with neutrons. The resultant 99 Mo decays with a half-life of 66 hours to the metastable state of Tc. This process permits the production of 99m Tc for medical purposes.Since 99 Mo is a fission product of 235 U fission, it can be separated from the other fission products and used to generate 99m Tc.For medical purposes, the 99m Tc is used in the form of pertechnate, TcO 4 - . The technetium isotope 99m Tc is unusual in that it has a half-life for gamma emission of 6.03 hours.ince 99 Mo is a fission product of 235 U fission, it can be separated from the other fission products and used to generate 99m Tc.

Technetium-99m Technetium-99m. Technetium -99m is a widely used radioactive tracer isotope in Nuclear Medicine. It's gamma ray energy of about 140 keV is convenient for detection. The fact that both its physical half-life and its biological half-life are very short leads to very fast clearing from the body after an imaging process.he resultant 99 Mo decays with a half-life of 66 hours to the metastable state of Tc. This process permits the production of 99m Tc for medical purposes. Since 99 Mo is a fission product of 235 U fission, it can be separated from the other fission products and used to generate 99m Tc.

Technetium Facts This is because technetium produces beta particles without gamma rays. Technetium is the only element that is artificially produced. This property gives technetium its name, from the Greek for artificial.. Technetium is a radioactive metal that looks a lot like platinum. Technetium has the second largest magnetic penetration depth after niobium. Solid metallic technetium is shiny and has a slow rate of oxidation to tarnish in air. In its powdered form, technetium will burn.
