nuclide

 or nuclear species

Species of atom as characterized by the number of protons, neutrons, and the energy state of the nucleus. A nuclide is characterized by its mass number and its atomic number. To be regarded as distinct, a nuclide must have an energy content sufficient for a measurable lifetime, usually more than 10−10 second. Nuclear isomers, which have the same number of protons and neutrons but differ in energy content and radioactivity, are also distinct nuclides. Nuclides are associated with radioactive decay and may be stable or unstable. There are about 1,700 known nuclides, of which about 300 are stable and the rest radioactive.


nuclide [′nü‚klīd]
(nuclear physics)
A species of atom characterized by the number of protons, number of neutrons, and energy content in the nucleus, or alternatively by the atomic number, mass number, and atomic mass; to be regarded as a distinct nuclide, the atom must be capable of existing for a measurable lifetime, generally greater than 10-10second. Also known as nuclear species; species.

Nuclide

A species of atom that is characterized by the constitution of its nucleus, in particular by its atomic number Z and its neutron number A - Z, where A is the mass number. The total number of stable nuclides is approximately 275. About a dozen radioactive nuclides are found in nature, and hundreds of others have been created artificially.

One of the properties that makes most of the nuclides used in nuclear medicine so attractive for that purpose -- their short half-life--has the drawback of making it impractical to distribute these nuclides as Standard Reference Materials.
25, 2000 Rhombic Corporation (OTCBB:NUKE) announces that work has begun at the University of Illinois on the company's Disperse Composite Materials (DCM) technology to develop a low cost method to neutralize radio active wastes, especially the long lived nuclides which can be converted into stable nuclides.
