There are three principal techniques used to measure carbon 14 content of any given sample— gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry.

Gas proportional counting is a conventional radiometric dating technique that counts the beta particles emitted by a given sample. In this method, the carbon sample is first converted to carbon dioxide gas before measurement in gas proportional counters takes place.

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.

A vial with a sample is passed between two photomultipliers, and only when both devices register the flash of light that a count is made.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.In this method, the carbon 14 content is directly measured relative to the carbon 12 and carbon 13 present. Some inorganic matter, like a shell’s aragonite component, can also be dated as long as the mineral’s formation involved assimilation of carbon 14 in equilibrium with the atmosphere.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.
