Calculation of radiocarbon dates : ウィキペディア英語版 | Calculation of radiocarbon dates
Radiocarbon dating methods produce data that must then be further manipulated in order to calculate a resulting "radiocarbon age". ==Calculations==
The calculations to be performed on the measurements taken depend on the technology used, since beta counters measure the sample's radioactivity, whereas accelerator mass spectrometers (AMS) determine the ratio of the three different carbon isotopes in the sample.〔McNichol, Jull & Burr, "Converting AMS Data to Radiocarbon Values: Considerations and Conventions", pp. 313.〕
