Limitations of carbon 14 dating
There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry (AMS).
The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples.
There are essentially two parts in the process of radiocarbon dating through accelerator mass spectrometry.
One is the cyclotron, and the other is a tandem electrostatic accelerator.
Radiocarbon dating is the technique upon which chronologies of the late Pleistocene and Holocene have been built.
