One can then examine the result with a radiation detector, such as a geiger counter, to determine where the provided atoms ended up. Radionuclides of familiar elements such as carbon can serve as tracers because they are chemically very similar to the non-radioactive nuclides, so most chemical, biological, and ecological processes treat them in a near identical way. Radionuclides are used in two major ways: for their chemical properties and as sources of radiation. Synthetic isotopes are not naturally occurring on Earth, but they can be created by nuclear reactions. Trace radionuclides are those that occur in tiny amounts in nature either due to inherent rarity, or to half-lives that are significantly shorter than the age of the Earth. The parent produced in the reactor is molybdenum-99.

A typical example is the technetium-99m generator used in nuclear medicine. The parent is usually produced in a nuclear reactor. Radionuclide generators contain a parent isotope that decays to produce a radioisotope.Cyclotrons accelerate protons at a target to produce positron emitting radioisotopes e.g. Particle accelerators such as cyclotrons accelerate particles to bombard a target to produce radionuclides.The elements that have a large propensity to take up the neutrons in the reactor have a high Barnes Number. A typical product from a nuclear reactor is thallium-201 and Iridium-192. The neutrons activate elements placed within the reactor. Radioisotopes produced with nuclear reactors exploit the high flux of neutrons present.Despite their relatively 'short' half-lives, they are found in nature because their supply is always being replenished.ДЄrtificially produced radionuclides can be produced by nuclear reactors, particle accelerators or by radionuclide generators: Cosmogenic isotopes, such as carbon-14, are present because they are continually being formed in the atmosphere due to cosmic rays. They have shorter half-lives than primordial radionuclides. Secondary radionuclides are radiogenic isotopes derived from the decay of primordial radionuclides. Primordial radionuclides originate mainly from the interiors of stars and, like uranium and thorium, are still present because their half-lives are so long that they have not yet completely decayed. Naturally occurring radionuclides fall into three categories: primordial radionuclides, secondary radionuclides and cosmogenic radionuclides. However, they can also constitute real or perceived dangers. Radionuclides are often referred to by chemists and physicists as radioactive isotopes or radioisotopes, and play an important part in the technologies that provide us with food, water and good health. Radionuclides may occur naturally, but can also be artificially produced. These particles constitute ionizing radiation. The radionuclide, in this process, undergoes radioactive decay, and emits a gamma ray(s) and/or subatomic particles. ДЄ radionuclide is an atom with an unstable nucleus, which is a nucleus characterized by excess energy which is available to be imparted either to a newly-created radiation particle within the nucleus, or else to an atomic electron (see internal conversion).
