It tells us the absolute age of something, It is used when scientists want to see how old a fossil is.

The four types of radiometric dating are: Potassium, Uranium, Rubidium, and Carbon I hope thats the answer you were looking for:)
Sedimentary Rocks
According to radiometric dating the Earth is approximately 4.54 billion years old. This age is based on dating of meteorite material.
Radiometric dating can give us the absolute age of the rock. Trace fossils and the Law of Superposition can only provide the relative age of the rock. Radiometric dating is far more specific in formation analysis.

This is called absolute, isotopic, or radiometric dating.
Radio metric dating.
Radiometric dating is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.
Radiometric or Radio-active decay dating involves looking at certain radio-active isotopes in the rocks of the earth, such as potassium and argon. Certain Isotopes have a half life and decay into another isotope after a certain amount of years. Geochemists use these types of dating to determine the age of rocks and how long the crust has been forming and moving.

Using standard radiometric dating of rocks returned from the Moon by the Apollo missions.
Carbon 14 dating is the best known example of radiometric dating, but there are many others. Another example of radiometric dating is the dating of the age of geological formations on earth. The oldest known rocks on the earth that have been analyzed, have been dated back some 4.404 billion years.

Carbon 14 dating is one tpye of radiometric dating. It is used for destermiing the age of samples of one-living entities. See related links for more information.
