Radiometric datingradioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbonin 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 principlesradiometric dating methods are used in geochronology to establish the geologic time scale.
