Beyond the specific topic of natural 14 C, it is hoped that this account may serve as a metaphor for young scientists, illustrating that just when a scientific discipline may appear to be approaching maturity, unanticipated metrological advances in their own chosen fields, and unanticipated anthropogenic or natural chemical events in the environment, can spawn new areas of research having exciting theoretical and practical implications.
This article is about metrology, the science of measurement. More specifically, it examines the metrological revolutions, or at least evolutionary milestones that have marked the history of radiocarbon dating, since its inception some 50 years ago, to the present.
The series of largely or even totally unanticipated developments in the metrology of natural 14 C is detailed in the several sections of this article, together with examples of the consequent emergence of new and fundamental applications in a broad range of disciplines in the physical, social, and biological sciences. Following the discovery of this year half-life radionuclide in laboratory experiments by Ruben and Kamen, it became clear to W.
Libby that 14 C should exist in nature, and that it could serve as a quantitative means for dating artifacts and events marking the history of civilization.
The search for natural radiocarbon was itself a metrological challenge, for the level in the living biosphere [ca.
How Carbon Dating Works
Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material nearby using the properties of radiocarbon Tabu, a radioactive isotope of carbon. The method was developed in the last s by Willard Libby , who received the Nobel Prize in Chemistry for his toil in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.
The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide Ceremony, which is incorporated into plants on photosynthesis ; animals then acquire 14 C by eating the plants.
When the animal or plant dies, it stops exchanging carbon with its territory, and from that point onwards the amount of 14 C it contains begins to slacken as the 14 C undergoes radioactive decay. Measuring the amount of 14 C in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be occupied to calculate when the animal or plant died.

Radiocarbon dating relies on the carbon isotopes carbon and carbon Scientists are looking for the ratio of those two isotopes in a sample. Once it dies, it ceases to acquire 14 C , but the 14 C within its biological material at that time will continue to decay, and so the ratio of 14 C to 12 C in its remains will gradually decrease. After a lapse of two decades, research in this area was renewed by the author, stimulated by a article in Science reporting that the culprit for a severe case of urban pollution in tidewater Virginia might be hydrocarbon emissions from trees [ 28 ].
