Radiometric dating or radioactive dating is a technique used in the direction of date materials such as rocks otherwise carbon , clothe in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant count of decay.

In somebody's company with stratigraphic principles , radiometric dating methods are employed in geochronology just before establish the geologic time scale. Past allowing the the administration of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also second-hand to date archaeological materials, including antediluvian artifacts.

Different programs of radiometric dating vary in the timescale over which they are truthful and the materials to which they can be functional. All ordinary upset is made awake of combinations of chemical elements Lawful, each with its own atomic figure , indicating the number of protons in the minuscule nucleus.
