Liquid scintillation counting is another radiocarbon dating technique that was popular in the 1960s.In this method, the sample is in liquid form and a scintillator is added.Accelerator mass spectrometry (AMS) is a modern radiocarbon dating method that is considered to be the more efficient way to measure radiocarbon content of a sample.

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.Radiocarbon dating is essentially a method designed to measure residual radioactivity.Standard errors are also reported in a radiocarbon dating result, hence the “±” values.These values have been derived through statistical means.
