Question

In living things, what is the source of the carbon-14 that is used in radiocarbon dating?

Answer 1

In living things, the source of the carbon-14 that is used in radiocarbon dating would be the carbon dioxide in the atmosphere. Radiocarbon dating is a method of estimating the age of organic material. Hope this answers the question. Have a nice day.

Answer 2

The answer is:

Atmosphere

-CARBON DIOXIDE FROM THE ATMOSPHERE.

The Explanation:

The source of the carbon-14 on the earth is the effect of cosmic rays with nitrogen on the atmosphere layer, when the cosmic rays interact with the atoms of oxygen and nitrogen will produced a lighter and smaller particles like X rays and alpha particles and gamma rays, and by the ionization of the oxygen and nitrogen at the atmospheric layer and by a number of chemical reaction will lead to carbon-14 according to this reaction equation:

n + 14N → p + 14C
