Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.

It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.

The oldest known rocks on the earth that have been analyzed, have been dated back some 4.404 billion years.

Carbon dating actually contributes very little to the available evidence for evolutionary theory.

Example sentence: One of the early tests of radiometric dating was to estimate the age of the wood from an ancient Egyptian artifact, for which the age was already known from historical documents.

Radiocarbon dating can be done at a variety of research institutions including Woods Whole and UC Irvine.

Radiometric dating is far more specific in formation analysis.

Radioactive dating is also known as Radiometric dating.

The half-life of carbon-14 is only 5, 730 years so this method is mainly used for dating things from the last 50,000 years Two major dating methods applied to artifacts and fossils are stratagraphic dating (based upon the particular layer of rock of sediment in which the object is found) or radiometric dating (which is based on the decay rates of certain radioactive isotopes).
