75 datingsite Simple explanation of carbon 14 dating

All living things on Earth are made up of a high percentage of an element called carbon.

Most carbon on Earth is not radioactive, but a very small percentage is.

Thus, as living things take in carbon, they inevitably will take up a small amount of radioactive carbon into their bodies.

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.

For example, say a fossil is found that has 35% carbon 14 compared to the living sample. We can use a formula for carbon 14 dating to find the answer.

Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.

At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.

Suggestions are offered for experimental projects that would resolve these uncertainties.

In this paper I will discuss eight categories of carbon-14 models and their experimental implications.

So, the fossil is 8,680 years old, meaning the living organism died 8,680 years ago.

Radiocarbon dating is only effective for objects and fossils that are less than 50,000 years old.
