Carbon-14, (14 C), or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on February 27, 1940, by Martin Kamen and Sam. Radiocarbon dating (also referred to as carbon dating or carbon-14 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.. The method was developed in the late 1940s by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960. It is based on the fact that radiocarbon (14 (EN) «There is a lot of other evidence that suggests to many that the Shroud is older than the radiocarbon dates allow and so further research is certainly needed. C14-datering of koolstofdatering is een methode van radiometrische datering waarmee de ouderdom van organisch materiaal en ecofacten wordt bepaald met behulp van de isotoop koolstof-14.Koolstof-14 (14 C) is een isotoop van koolstof die in onze atmosfeer uit stikstofkernen gevormd wordt.Dit gebeurt door kernreacties ten gevolge van de kosmische straling waaraan de aarde voortdurend blootstaat. 2014 April 25, Martin Lukacs, “Canada becoming launch-pad of a global tar sands and oil shale frenzy”, in The Guardian Weekly, volume 190, number 20, page 13: If Alberta’s reserves are a carbon bomb, this global expansion of tar sands and oil shale exploitation amounts to an escalating emissions arms race, the unlocking of a subterranean cache of weapons of mass ecological destruction. Il carbonio-14, 14 C (o radiocarbonio) è un isotopo radioattivo del carbonio avente 6 protoni e 8 neutroni.Il carbonio-14 fu scoperto il 27 febbraio 1940 da Martin Kamen e Sam Ruben al laboratorio radiologico dell'Università della California a Berkeley, ma la sua esistenza era già stata ipotizzata da Franz Kurie nel 1934. El carbono-14, 14 C o radiocarbono, es un isótopo radioactivo del carbono, descubierto el 27 de febrero de 1940 por Martin Kamen y Sam Ruben.Su núcleo contiene 6 protones y 8 neutrones. Willard Libby determinó un valor para el periodo de semidesintegración o semivida de este isótopo: 5568 años. Determinaciones posteriores en Cambridge produjeron un valor de 5730 años.
