stable isotope
n.
An isotope of an element that shows no tendency to undergo radioactive breakdown.

isotope [i´so-tōp]
a chemical element having the same atomic number as another (i.e., the same number of nuclear protons), but having a different atomic mass (i.e., a different number of nuclear neutrons).
radioactive isotope radioisotope.
stable isotope one that does not transmute into another element with emission of corpuscular or electromagnetic radiations.

isotope (ī´sōtōp),
n one of several nuclides having the same number of protons in their nuclei, and hence having the same atomic number but differing in the number of neutrons, and therefore in the mass number. The isotopes of a particular element have virtually identical chemical properties.
isotope, stable,
n a nonradioactive isotope of an element.

stable,
adj the term applied to a substance that has no tendency to decompose spontaneously. As applied to chemical compounds, it denotes their ability to resist chemical alterations.
stable isotope,
n See isotope.

isotope
a chemical element having the same atomic number as another (i.e. the same number of nuclear protons), but having a different atomic mass (i.e. a different number of nuclear neutrons).

radioactive isotope
one having an unstable nucleus and which emits characteristic radiation during its decay to a stable form. See also radioisotope.
stable isotope
one that does not transmute into another element with emission of corpuscular or electromagnetic radiations.

The researchers accumulated carbon and nitrogen stable isotope data from fossilized remains of humans in Europe, which pointed towards a significant shift in the range of animal resources exploited with the spread of modern humans into Europe 40,000 years ago.
To determine the bioavailability of calcium in the modified carrots, 30 volunteers-15 females and 15 males of various ethnic backgrounds and in their early to late 20s--ate single meals containing regular or modified carrots, which were labeled with a stable isotope of calcium.
ABSTRACT Controlled feeding experiments with juvenile abalone Haliotis discus hannai were performed to evaluate the suitability of stable isotope analyses for diet inference.
