To get to that point, there is also a historical discussion and description of non-radiometric dating methods.The example used here contrasts sharply with the way conventional scientific dating methods are characterized by some critics (for example, refer to discussion in "Common Creationist Criticisms of Mainstream Dating Methods" in the Age of the Earth FAQ and Isochron Dating FAQ).Radioactive isotopes are used for radioactive dating.For example, you would use radioactive isotope Carbon-14 to date anything under 70,000 years that was once living.Radiocarbon dating is an radioactive isotope dating technique used in dating materials which contain the unstable carbon-14 isotope.

so geological dating is usually done by looking for pairs of elements bound in the rocks.A radioactive isotope is a chemical element that has an unstable nucleus subject to decay. The percent of the radioactive isotope in the specimen is accumulated to normal levels as the thing was alive, after it is dead it… They use an isotope (Technetium-99) which decays into the slowly-decaying radioisotope Technetium-98..they use this because, with a medically-useful half-life of a little over six hours, the patient is exposed to radiation for only as long as he or she needs to be. The half lives of carbon isotopes are derived by studying their radioactive decay.Radioactive isotopes are used in medicine, such as in chemical stress tests, and one radioactive isotope, carbon-14, is used to date fossils. Carbon dating is a process that scientists use to try to ascertain the age of an item by analyzing the amount of a radioactive carbon isotope that is present in the item. For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years.Radioactive isotopes decay from their parent isotope to daughter isotope at a constant rate (under any circumstances).The rate at which a parent isotope decays to its daughter isotope is considered one half life.
