What can radiocarbon dating be used on

This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.

The two views are aligned along the midplane of the body and point in opposite directions.

The front and back views of the head nearly meet at the middle of the cloth.

The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles.

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

) is a length of linen cloth bearing the image of a man who is alleged to be Jesus of Nazareth.

The cloth itself is believed by some to be the burial shroud he was wrapped in when he was buried after crucifixion although three radiocarbon dating tests in 1988 dated a sample of the cloth to the Middle Ages.

A variety of methods have been proposed for the formation of the image, but the actual method used has not yet been conclusively identified.

Despite numerous investigations and tests, the status of the Shroud of Turin remains murky, and the nature of the image and how it was fixed on the cloth remain puzzling.

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.

Where t is the age of the fossil (or the date of death) and ln() is the natural logarithm function.

Reddish-brown stains are found on the cloth, showing various wounds that, according to proponents, correlate with the yellowish image, the pathophysiology of crucifixion, and the Biblical description of the death of Jesus.
