Standard errors are also reported in a radiocarbon dating result, hence the “±” values.

These values have been derived through statistical means.

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.By knowing how much carbon 14 is left in a sample, the age of the organism when it died can be known.It must be noted though that radiocarbon dating results indicate when the organism was alive but not when a material from that organism was used.
