Video details
Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , 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 rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.

What Half Life Means for Evolution

The long, slow decay of carbon allows archaeologists to accurately date the relics of history back to 60, years. And while the carbon dating technique is well known and understood the ratio of carbon to other carbon isotopes is measured to determine the age of objects containing the remnants of any living thing , the reason for carbon's slow decay has not been understood. Why, exactly, does carbon have a half-life of nearly 6, years while other light atomic nuclei have half-lives of minutes or seconds? Half-life is the time it takes for the nuclei in a sample to decay to half the original amount. The reason involves the strong three-nucleon forces a nucleon is either a neutron or a proton within each carbon nucleus. It's all about the simultaneous interactions among any three nucleons and the resulting influence on the decay of carbon And it's no easy task to simulate those interactions.

Carbon dating , also called radiocarbon dating , method of age determination that depends upon the decay to nitrogen of radiocarbon carbon Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle : it is absorbed from the air by green plants and then passed on to animals through the food chain. Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
