Carbon 14 dating simple explanation
Animals eat plants and/or other animals; humans eat plants and animals.
Therefore all living plants, animals, and human beings have the same amount of carbon-14 in their bodies at the same time.
Carbon-14 is present in all living things in minute amounts.
There are exceptions to the theories and relationships introduced below that are beyond the scope of this discussion.
Carbon is the basis of life and is present in all living things.
It then uses this information to determine the last time the fossil was respiring carbon (i.e. A radiocarbon dating lab is able to do this using the known “half-life” of carbon-14.
The half-life of carbon-14 is the amount of time it takes for one-half of the original amount to disappear by radioactive decay.
Carbon-14 originates in the upper atmosphere of the earth and is created when neutrons originating from solar radiation bombardment collide with nitrogen in the air.
