Carbon-14 dating is normally used by archaeologists rather than geologists because it ceases to be accurate at ages over 50,000-60,000 years.The half life of carbon 14 is about 5,000 years, so it becomes increasingly difficult to detect at time… For instance, Carbon by convention has 12 components to it's nucleus (6 protons with a positive charge, and 6 neutrons without any charge) but carbon compounds also contain a radioactive isotope called carbon 14 which has an additional 2…That is the time duration that is used for radiometric dating.The technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material is called radioactive dating.

- Uranium-Lead method - Rubidium-Strontium method - Carbon-14 method – also known as carbon dating.

Because radioactive decay follows a specific mathematical formula and is dependent upon unique decay rates (half-lives) of each element, formulas can be developed that compare the measured amounts of different elemental isotopes.
