Definiton of radiometric dating mtvsex2k dating documentary
Carbon-14 has a half-life of approximately 5,730 years and produces the decay product nitrogen-14.
The half-life is the amount of time it takes for half of the atoms of a specific isotope to decay.Radioactive dating enables geologists to record the history of the earth and its events, such as the dinosaur era, within what they call the geologic time scale.Radioactive dating uses the ratios of isotopes and their specific decay products to determine the ages of rocks, fossils and other substances.The disintegration of the neutrons within the atom of the element's nucleus is what scientists call radioactivity.An isotope disintegrates at a constant rate called the half-life --the time it takes for half the atoms of a sample to decay. By counting the number of half-lives and the percentages remaining of parent and daughter isotopes, scientists are able to determine what they call the absolute age of a discovery.
