Difference between radiometric hookup and radiocarbon hookup

opinion

Radiometric dating or radioactive dating is a technique 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. 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.

Radiometric dating is also used to date archaeological materials, including ancient artifacts.
