It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.

This scintillator produces a flash of light when it interacts with a beta particle.

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.

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.

This means that small amounts of Carbon-14 are present in your body whenever you breathe in, or eat.

Carbon-14 unlike Carbon-12 or 13 is unstable and slowly decays into Nitrogen-14 over the course of thousands of years.

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.

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.

The method does not count beta particles but the number of carbon atoms present in the sample and the proportion of the isotopes. Samples that have been radiocarbon dated since the inception of the method include charcoal, wood, twigs, seeds, bones, shells, leather, peat, lake mud, soil, hair, pottery, pollen, wall paintings, corals, blood residues, fabrics, paper or parchment, resins, and water, among others.
