As a result, animal and plant life regularly assimilate carbon 14 atom together with the usual carbon 12.
These neutrons, once freed, can interact with atoms of nitrogen 14 in air, causing the expulsion of a proton and the formation of carbon 14.
This assimilation stops upon the death of the organism, thus halting the absorption of any more carbon 14.
The atoms of carbon 14 then proceed to decay exponentially, with a half life of 5,700 years.
Humans have been aware of carbon since the earliest of times. The black color of smoke is caused by unburned specks of carbon.
The smoke may have collected on the ceiling of their caves as soot.
The ratio of the activities of the fossilized and living bodies then provides an age.
