Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale. This method involves comparing the ratio of radioactive isotopes in the fossil to Different radioisotopes have different half lives and are thus useful for dating. Radioactive Dating Radioactive dating is a method of determining the approximate age of an old object by measuring the amount of a known radioactive element it contains.
