Every chemical element has one or more radioactive isotopes.More than 1,800 radioactive isotopes of the various elements are known.Some of these are found in nature; the rest are produced artificially as the direct products of nuclear reactions or indirectly as the radioactive descendants of these products.All rocks and minerals contain long-lived radioactive elements that were incorporated into Earth when the Solar System formed.

These radioactive elements constitute independent clocks that allow geologists to determine the age of the rocks in which they occur.Radiometric dating (often called radioactive dating) is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
