It is one of the most accurate dating methods and it is completely natrual.
It is used with C-14 which is an unstable element made from atmospheric nitrogen that has been boken down. it is then delivered down to earth through atmospheric activity, storms for instance.
Discovered by: Willard Libby and J. Arnold.
There are two isotopes of carbon that are used to carbon date a substance. This is because the half life of carbon is well known to scientists.

Radiocarbon dating is a tool for archaeologists to know the age of materials. The method can tell scientists when a living organism died but not how it died. Radiocarbon dating has an industrial application developed by the ASTM. The method, called ASTM D6866, quantifies the biomass fraction of materials. The USDA BioPreferred Program, for example, requires ASTM D6866 to determine the biobased content of products. The US EPA also requires ASTM D6866 to determine the biogenic or renewable carbon fraction of carbon dioxide emissions from manufacturing plants that use a mix of coal and biomass as fuels.
In most cases radiocarbon dating is the most commonly used method for dating an artifact made from a material which was once part of a living organism. However, there are other methods available. Although radiometric dating is a useful tool dendrochronology (also known as tree ring dating) remains the most effective and accurate method of dating certain species of wood (where a suitable sample can be found).

Radiocarbon dating
Carbon 14 in scientific terms can refer to carbon 14 dating or radiocarbon dating. This is a method of age determination that relies on the decay of radiocarbon to nitrogen.
Radiocarbon dating.
Radio metric dating.
Radiocarbon dating is an absolute, (it is used provides a calender year/s for a particular event), radiometric (it is based on the known decay rate of a radioactive isotope) dating method.
Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. Measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying 14 C atoms in a sample.

There are two isotopes of carbon that are used to carbon date a substance. This is because the half life of carbon is well known to scientists.
They are completely unrelated - except for their purpose, which is to find out how old something is.Dendochronology uses tree ring counting. Radiocarbon uses radioactive decay.
The radiocarbon method was developed by a team of scientists led by the late Professor Willard F. Libby of the University of Chicago after the end of World War 2. Libby later received the Nobel Prize in Chemistry in 1960 for the radiocarbon discovery. Libby made his first test before 1960.
Through Radiocarbon dating, the age of an object can be determined by using the properties of radiocarbon, a radioactive isotope of carbon. This method was invented by Willard Libby in the late 1940s.
The method of radioactive dating used for the Turin Shroud was 'radiocarbon dating' and was invented by Willard Libby.Source and for more information please see:http://en.wikipedia.org/wiki/Radiocarbon_dating
