For radiocarbon dating to be possible, the material must once have been part of a living organism.

As explained below, the radiocarbon date tells us when the organism was alive (not when the material was used).

This fact should always be remembered when using radiocarbon dates.

From this science, we are able to approximate the date at which the organism were living on Earth.

Radiocarbon dating is used in many fields to learn information about the past conditions of organisms and the environments present on Earth.

He first noted that the cells of all living things contain atoms taken in from the organism's environment, including carbon; all organic compounds contain carbon.

Most carbon consists of the isotopes carbon 12 and carbon 13, which are very stable.

Radiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method.

It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old. Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.

A very small percentage of carbon, however, consists of the isotope carbon 14, or radiocarbon, which is unstable.
