The method was developed in the late 1940s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960.

It is based on the fact that radiocarbon ( 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 used to calculate when the animal or plant died.

The ratio of λ is a constant that depends on the particular isotope; for a given isotope it is equal to the reciprocal of the mean-life – i.e.

the average or expected time a given atom will survive before undergoing radioactive decay. The calculations involve several steps and include an intermediate value called the "radiocarbon age", which is the age in "radiocarbon years" of the sample: an age quoted in radiocarbon years means that no calibration curve has been used − the calculations for radiocarbon years assume that the atmospheric For consistency with these early papers, it was agreed at the 1962 Radiocarbon Conference in Cambridge (UK) to use the “Libby half-life” of 5568 years.

When a date is quoted, the reader should be aware that if it is an uncalibrated date (a term used for dates given in radiocarbon years) it may differ substantially from the best estimate of the actual calendar date, both because it uses the wrong value for the half-life of and each component is also referred to individually as a carbon exchange reservoir.

The different elements of the carbon exchange reservoir vary in how much carbon they store, and in how long it takes for the These organisms contain about 1.3% of the carbon in the reservoir; sea organisms have a mass of less than 1% of those on land and are not shown on the diagram.

The following was published yesterday, March 22, 2019, in Archaeometry, a Wiley publication.

The development of radiocarbon dating has had a profound impact on archaeology.The results were summarized in a paper in Science in 1947, in which the authors commented that their results implied it would be possible to date materials containing carbon of organic origin.Libby and James Arnold proceeded to test the radiocarbon dating theory by analyzing samples with known ages.Radiocarbon ages are still calculated using this half-life, and are known as "Conventional Radiocarbon Age".Since the calibration curve (Int Cal) also reports past atmospheric concentration using this conventional age, any conventional ages calibrated against the Int Cal curve will produce a correct calibrated age.
