Source carbon 14 used radiocarbon dating

And say that every 5,568 years you add another gallon of water to the mixture.Doing that basically cuts the concentration of blue dye in half.So, the fossil is 8,680 years old, meaning the living organism died 8,680 years ago.Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.

It is naturally unstable and so it will spontaneously decay back into N-14 after a period of time.After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze.C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope).
