Isotopes used in radiocarbon dating

Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.C-14 is formed in the upper atmosphere by nuclear reactions initiated by neutrons in cosmic radiation ( and convert it to organic compounds, and in this way, C-14 becomes incorporated into living tissue.When the plant dies, C-14 will no longer be taken up.It is present in small amounts in most organic matter and has a half-life of approximately 5730 years.Living organisms take in this carbon and use it for growth.

Atomic bomb detonations since 1950 have boosted the amount of C-14 in the atmosphere and, as a result of this, a method has been devised to date recent samples.

In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.
