Technetium in Diagnostic Nuclear Medicine(2) 99m Tc is one of the most widely used isotopes in nuclear medicine. It is injected into the patient in the form of a saline solution of a compound, chosen because it will be absorbed by the organ under investigation, which can then be "imaged" by an X-ray camera or scanner.
Technetium is found in the spectrum of S-, M-, and N-type stars, leading to new theories of the production of heavy elements in the stars. Technetium is a silver-gray metal and is the first element to be made artificially. It has 21 isotopes, all of which are radioactive, allowing for its use in medical radioactive isotope tests. ...
Technetium is a silvery-gray radioactive metal with an appearance similar to platinum, commonly obtained as a gray powder. [20] The crystal structure of the bulk pure metal is hexagonal close-packed. The crystal structure of the nanodisperse pure metal is cubic.
Radionuclides are present in groundwater at contaminated nuclear facilities with technetium-99, one of the most mobile radionuclides encountered. In situ bioremediation via the generation of microbially reducing conditions has the potential to remove aqueous and mobile Tc(VII) from groundwater as insoluble Tc(IV). However, questions remain ...

Atomic Number – Protons, Electrons and Neutrons in Technetium. Technetium is a chemical element with atomic number 43 which means there are 43 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 …
Technetium-99 is a beta emitting radionuclide with a half-life of 2.1 × 10 5 years. It is released into the environment from nuclear power reactors, nuclear wastes, reprocessing facilities, and from testing nuclear weapons. It exists in as many as 19 isotopes, and in multiple oxidations states (0, +3, +4, +5, +6, +7).

Technetium ist ein chemisches Element mit dem Elementsymbol Tc und der Ordnungszahl 43. Es kommt auf der Erde natürlicherweise vor, wenn auch in sehr geringen Mengen. Technetium war das erste künstlich hergestellte Element und erhielt deswegen seinen aus dem altgriechischen Wort τεχνητός technētós („künstlich") hergeleiteten Namen.. Es zählt zu den …

Technetium also has numerous meta states. 97m Tc is the most stable, with a half-life of 91.0 days (0.097 MeV). This is followed by 95m Tc (half-life: 61 days, 0.038 MeV) and 99m Tc (half-life: 6.04 hours, 0.143 MeV). 99m Tc only emits gamma rays, subsequently decaying to 99 Tc. For isotopes lighter than 98 Tc, the primary decay mode is ...

Technetium is a fission product of uranium and does not occur naturally, and there are no non-radioactive isotopes of Tc. Technetium-99 (half-life = 2.1 × 10 5 years), is the most common isotope found in water. The oxidized form of technetium, the pertechnetate anion (TcO 4− ), is very soluble and mobile in groundwater.
Technetium is found in the spectrum of S-, M-, and N-type stars, leading to new theories of the production of heavy elements in the stars. Technetium is a silver-gray metal and is the first element to be made artificially. It has 21 isotopes, all of which are radioactive, allowing for its use in medical radioactive isotope tests.

a Technetium-99m. Technetium-99m has been used as an SPECT isotope for decades and is considered to be the most widely employed diagnostic radionuclide (Rösch and Knapp, 2011; Synowiecki et al., 2018).While several methods have been employed to generate 99m Tc from high specific activity 99 Mo, the acidic alumina column approach found the most popularity; the …

What is it used for?
Technetium is highly radioactive and is only found naturally on the earth's crust. It can be created by bombarding molybdenum-98 with neutrons. Technetium is commercially produced as a byproduct from nuclear reactors and from the detonation of nuclear weapons. Technetium-99 can be used to help perform diagnostic tests ...
