There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon-12, carbon-13 and carbon-14.

The unstable nature of carbon 14 (with a precise half-life that makes it easy to measure) means it is ideal as an absolute dating method.

Radiocarbon dating is a method of estimating the age of organic material.

It was developed right after World War II by Willard F.

It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.

In 1979, Desmond Clark said of the method “we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation” (3).

Age determinations can also be obtained from carbonate deposits such as calcite, dissolved carbon dioxide, and carbonates in ocean, lake, and groundwater sources.

There is a small amount of radioactive carbon-14 in all living organisms because it enters the food chain.

Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.

The results showed that Ötzi died over 5000 years ago, sometime between 33 BC. It is found in the air in carbon dioxide molecules.

Materials that originally came from living things, such as wood and natural fibres, can be dated by measuring the amount of carbon-14 they contain.

For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.
