Carbon dating is a technique used to determine the approximate age of once-living materials. It is based on the decay rate of the radioactive carbon isotope 14 C, a form of carbon taken in by all living organisms while they are alive. Before the twentieth century, determining the age of ancient fossils or artifacts was considered the job of paleontologists or paleontologists, not nuclear physicists. By comparing the placement of objects with the age of the rock and silt layers in which they were found, scientists could usually make a general estimate of their age.

However, many objects were found in caves, frozen in ice , or in other areas whose ages were not known; in these cases, it was clear that a method for dating the actual object was necessary. In , the American chemist Bertram Boltwood — proposed that rocks containing radioactive uranium could be dated by measuring the amount of lead in the sample.

This was because uranium, as it underwent radioactive decay , would transmute into lead over a long span of time. Thus, the greater the amount of lead, the older the rock. Boltwood used this method, called radioactive dating , to obtain a very accurate measurement of the age of Earth. While the uranium-lead dating method was limited being only applicable to samples containing uranium , it was proved to scientists that radioactive dating was both possible and reliable.

The first method for dating organic objects such as the remains of plants and animals was developed by another American chemist, Willard Libby — He became intrigued by carbon — 14, a radioactive isotope of carbon.

Various tests of reliability have confirmed the value of carbon data, and many examples provide an interesting range of application. So in the real world, looking at a sample like say a bone dug up by an archaeologist, how do we know how much carbon 14 we started with?

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. Now living plants 'breathe' CO 2 indiscriminately they don't care about isotopes one way or the other , and so while they are living they have the same ratio of carbon 14 in them as the atmosphere. Background samples analyzed are usually geological in origin of infinite age such as coal, lignite, and limestone.

Measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying 14 C atoms in a sample. There are two types of testing technology: Thank You for Your Contribution!

The results were summarized in a paper in Science in , in which the authors commented that their results implied it would be possible to date materials containing carbon of organic origin. The calculations given above produce dates in radiocarbon years:
