What is radiometric dating and how is it used
An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.Background radiocarbon activity is measured, and the values obtained are deducted from the sample’s radiocarbon dating results.
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.
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.
