an unstable form of a nuclide Nuclides & Isotopes Radionuclides [] [ Click "BackButton" for previous location
Any manÂmade or natural element which emits radiation in the form of alpha or beta particles, or as gamma rays.
Any species of an atom that is radioactive.
a radioactive isotope; an isotope that undergoes radioactive decay.
any radioactive isotope.
An atom characterized by the composition of its nucleus, and consequently, the quantity of protons, neutrons, and energy.
An unstable form of an element that can decay and give off radiation is a radionuclide. Radionuclide is the same as radioisotope. [Back to Module 2
a radioactive element contained in a radioactive compound
A radioactive atom as characterized by the number of neutrons and protons in its nucleus.
A nuclide that decays spontaneously, emitting ionizing radiation.
Any nuclide (isotope of an element) which exhibits radioactivity (ie can undergo spontaneous disintegration, releasing an alpha-particle, a beta-particle or a gamma-ray).
Radioactive atoms that are used to make a tracer signal that is picked up in a bone scan.
a nuclide with an unstable nucleus
An atom which is unstable and which may undergo spontaneous decay to another atom by emission or ionising
Nuclide that exhibits radioactivity.
An atom of a radioisotope. A radioactive atom defined by its proton number, nucleon number and energy state. Thus it is not only clearly identified as a particular radioisotope of that atom but also its energy state is clearly defined giving an indication of whether it will emit a gamma ray to attain a more stable lower energy state.
A radioactive species of atom characterized by the makeup of its nucleus (the number of protons, the number of neutrons, and the energy content) which causes the nucleus to be unstable.
an isotope of an element which is unstable, because it has an unbalanced number of protons and neutrons
a radioactive substance used as a "tracer," which means it travels through the blood stream and is taken up (absorbed) by the healthy heart muscle tissue
a type of atom that spontaneously undergoes radioactive decay
is a type of atom that spontaneously undergoes radioactive daecay. Radionuclides are hazardous substances under MTCA. ( MTCA, p21)
An unstable nuclide that emits ionizing radiation.
A radioactive element or substance.
An unstable form of a chemical element that radioactively decays, resulting in the emission of nuclear radiation.
Radioactive atoms used in tiny amounts as a tracer in a bone scan.
radioactive nuclear species or nuclide. A to F | G to L | M to R | S to Z
A radioactive nuclide that spontaneously exhibits radioactive decay.
an unstable and therefore radioactive form of a nuclide.
An element characterized according to its atomic mass and atomic number that is radioactive.
A material with an unstable atomic nucleus that spontaneously decays or disintegrates, producing radiation.
A radioactive element characterized according to its atomic mass and atomic number that can be manmade or naturally occurring.
a radioactive nuclide; one that disintegrates with the emission of corpuscular or electromagnetic radiations
A radioactive nucleus of a compound or element.
radioactive nuclide. Often used to distinguish radioisotopes of different chemical elements, such as iodine 131 and uranium 239.
Any nuclide which is unstable and undergoes natural radioactive decay.
A radioactive isotope. See also nuclide.
A radioactive nuclide. Radioactivity is the property possessed by some elements, such as uranium; or isotopes, such as carbon 14; of spontaneously emitting energetic particles, such as electrons or alpha particles, by the disintegration of their atomic nuclei.
Any man-made or natural element that emits radiation.
A radioactive species of an atom.
a type of atom that releases radiation in the form of gamma rays.
THE RADIOACTIVE PART OF THE RADIOPHARMACEUTICAL.
A radioactive nuclide (atom).
A radioactive atomic nucleus.
A naturally occurring or artificially produced radioactive element or isotope.
The naturally occurring or artificially produced radioactive form of an element.
A radioactive isotope of an element.
An unstable nuclide that emits ionising radiation.
Radioactive particle, man-made (anthropogenic) or natural, with a distinct atomic weight number. Can have a long life as soil or water pollutant.
A radionuclide is an atom with an unstable nucleus. The radionuclide undergoes radioactive decay by emitting a gamma ray(s) and/or subatomic particles. Radionuclides may occur naturally, but can also be artificially produced.
