Methods of radiocarbon dating
Background radiocarbon activity is measured, and the values obtained are deducted from the sample’s radiocarbon dating results.
Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.
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.
When the stocks of Oxalic Acid I were almost fully consumed, another standard was made from a crop of 1977 French beet molasses.
The new standard, Oxalic Acid II, was proven to have only a slight difference with Oxalic Acid I in terms of radiocarbon content.
