The sample passes through several accelerators in order to remove as many atoms as possible until the C pass into the detector.

Increasingly though, students are learning about the principles of radiocarbon dates in archaeology, palaeontology and climate science degrees and can combine cross-disciplinary studies.

This does not mean that we have a precise year of 3780BC, it means we then need to calibrate through other methods that will show us how atmospheric concentrations of the C isotope has changed - most typically through the dendrochronology records (tree ring data) (10).

Very old trees such as North American Bristlecone Pine are ideal for constructing long and accurate records of the state of the atmosphere.

This new method was based on gas and liquid scintillation counting and these methods are still used today, having been demonstrated as more accurate than Libby's original method (3).

Willard Libby would receive a Nobel Prize for Chemistry in 1960.

There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon-12, carbon-13 and carbon-14.
