Dating uses the properties of atoms
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.
Standard errors are also reported in a radiocarbon dating result, hence the “±” values.
The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.Background radiocarbon activity is measured, and the values obtained are deducted from the sample’s radiocarbon dating results.Background samples analyzed are usually geological in origin of infinite age such as coal, lignite, and limestone.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.
The radiocarbon age of a certain sample of unknown age can be determined by measuring its carbon 14 content and comparing the result to the carbon 14 activity in modern and background samples.
