Where does technetium come from?

Technetium occurs naturally as a spontaneous fission product in uranium and thorium ores, the most frequent sources, or as a result of neutron capture in molybdenum ores. It can also be produced by irradiating zinc dust with neutrons.

Technetium has many applications including use as a component of smoke detectors and nuclear medicine imaging agents. Technetium-99m is used in more than 90% of all radiocontrast examinations because it is easily detected by gamma cameras. Also used for bone scans and other medical procedures. Technetium-186 is used to study brain function because it enters brain cells where it emits low energy photons that can be detected using modern scanning technology.

The majority of technetium is obtained from nuclear reactors but it can also be found in coal mines, metal smelters, and rock formations resulting from radioactive decay. The half-life of technetium is about a million years which makes it useful for long-term storage projects.

Technetium was first discovered in 1938 by Edwin McMillan who was studying minerals from the Oak Ridge National Laboratory near Tennessee. He noticed the elements was present in some samples of uranium ore but not others. Subsequently, other scientists have confirmed this finding. Technetium is a rare earth element with symbol Tc and atomic number 44.

Where is technetium commonly found?

Technetium has been discovered naturally occurring in trace amounts in uranium ore. Technetium-99 is created from the byproducts of uranium nuclear fuel. Although it is a rare element, it is also a very powerful one. Technetium can only be manufactured in small quantities for scientific research purposes.

Technetium is used in special alloys called "technetium metals" that are highly resistant to corrosion and heat. These alloys are used in jet engines, rocket motors, and nuclear reactors because they do not react with oxygen or nitrogen at normal temperatures. The most common use of technetium is in medical imaging procedures such as x-rays and MRI scans.

X-rays are used to see inside people's bodies without invasive surgery. X-rays show bones, teeth, and other dense objects such as tumors. Nuclear medicine uses radioactive materials for diagnostic tests and to treat cancer patients. Technetium is used in about two thirds of all nuclear medicine tests because it is located in many healthy organs where it does not cause problems for the patient. It is also used in bone scanning technology to identify osteoporosis (loss of bone mass) and other diseases that affect the skeleton.

MRI scans are another way to see inside people's bodies without surgery.

Where does technetium come from in the body?

He examined molybdenum that had been subjected to high-energy radiation and determined that it contained the element. Technetium is a silvery-grey metal that oxidizes slowly in wet air. Technetium is found in trace amounts in uranium ore. The isotope technetium-99 may be created from uranium nuclear reactor waste. Technetium-99 has a half life of about 5520 years, so it should still be present in the environment even though uranium itself is not. Technetium was first discovered by Karl Jannsen and Edward Moorhouse in 1951 when they uncovered it while searching for new elements using mass spectrometry.

Technetium is used in small quantities in certain medicines and industrial processes. It is also used as a radioactive tracer in medicine (for example, in bone scans to show where in the body there is too much or not enough calcium). Technetium decays into molybdenum over time if it is not used in some way (such as in medicine). Molybdenum is an element that is sometimes used in catalysts. Uranium compounds are converted into technetium during research experiments at nuclear facilities such as hospitals or universities. The resulting material is called "technetium-99". This isotope is useful because it stays inside the body for a long time; this allows doctors to track where in the body fluids flow after injection.

How is technetium created?

Technetium was generated by hitting molybdenum atoms with deuterons accelerated by a device known as a cyclotron. Technetium is now created by bombarding molybdenum-98 with neutrons. When molybdenum-98 absorbs a neutron, it transforms into molybdenum-99. Molybdenum-99 will continue to transform itself into technetium-99m through beta decay.

When an atom loses an electron, another atom can acquire that electron. In chemistry this process is called oxidation. Atoms are oxidized when other elements are added to them. For example, iron can be oxidized when treated with oxygen in air. Iron (II) compounds are converted into iron (III) compounds. Other elements can be oxidized too. For example, copper can be oxidized when exposed to air at room temperature. Copper (I) compounds are turned into copper (II) compounds.

Elements can be reduced too. This means that an atom loses electrons. Elements are reduced when other elements are taken away from them. For example, uranium is reduced when treated with hydrogen gas at 300°C. Uranium (IV) compounds are transformed into uranium (III) compounds. Now that you know the two ways that technetium can be made, let's see how it is used in medicine.
