Useful links to online information are on the website Lesson time can then be devoted to checking students understanding and consolidating learning.By knowing how much carbon 14 is left in a sample, the age of the organism when it died can be known.

The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.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.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.
