This method of prescreening is now regularly used at the Oxford Radiocarbon Accelerator Unit (ORAU).

Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.

Radiocarbon dating has been one of the most significant discoveries in 20th century science.

DR CHRISTINE PRIOR In conventional radiocarbon dating, you’re measuring the presence of the C-14 when you measure the radioactive decay.

The C-14 decays with the beta particle, and you have some detection equipment and you count the C-14s one by one.

Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).

Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.

land is debated as earlier studies and different archaeological sources seemingly provide conflicting interpretations.

The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.

The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.

Accelerator mass spectrometry is not dependent upon the radioactive decay.
