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.

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.

Beta Analytic provided this format from around 1995 to early 2017.

The age ranges generated by the program must be considered as approximations.

In this method, when multiple calibration ranges are reported, all the ranges are considered to be equally likely.

This method is the most conservative indication of calendar age.

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.

Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.
