Radiocarbon dating is one kind of radiometric dating, used for determining the age of organic remains that are less than 50,000 years old.For inorganic matter and for older materials, isotopes of other elements, such as potassium, uranium, and strontium, are used.The method compares the amount of a naturally occurring radioactive isotope and its decay products, in samples. It is the main way to learn the age of rocks and other geological features, including the age of the Earth itself.It may be used to date a wide range of natural and man-made materials.
The method works best if neither the parent nuclide nor the daughter product enters or leaves the material after its formation.
Anything which changes the relative amounts of the two isotopes (original and daughter) must be noted, and avoided if possible.
Contamination from outside, or the loss of isotopes at any time from the rock's original formation, would change the result.
Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.
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.
