Rearrangements can occur, leading to the emission of radiation.

Of the 3,000 nuclides (distinct kind of atom) known, only about 300 are stable.

Only a very small amount of americium is used – about 0.2 mg.

It has a half-life of 432 years and is an alpha particle emitter.

It is also used in the food industry to delay the ripening of fruits, to inhibit the production of shoots and buds in vegetables such as potatoes and to improve the shelf-life of fruits.

It is therefore important to continually refine our interpretation of hydrogeologic, geochemical and isotopic data to better understand the spatial and temporal movement of water in the subsurface.

Both alpha and beta particles would not pass through pipes, so could not be used.

Radioactive sources (most commonly Technetium-99 or sometimes Iodine-123) can be used by doctors to find out if different organs in our bodies are working properly (eg. Doctors can inject a small amount of radioactive substance into a patient's body.

Closer examination of the atoms that make up a given element has shown that, although they have the same number of protons, they can have differing numbers of neutrons.

For example, the element carbon has three naturally occurring atomic forms – Some arrangements of the protons and neutrons in atomic nuclei are in a state of high energy and are said to unstable.

Strontium-90, which is a gamma ray emitter, is used as part of the control system operating the compression rollers.
