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.Radiocarbon dating is essentially a method designed to measure residual radioactivity.By knowing how much carbon 14 is left in a sample, the age of the organism when it died can be known.

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.Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes.When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.In this method, the sample is in liquid form and a scintillator is added.This scintillator produces a flash of light when it interacts with a beta particle.
