Number 14 in carbon 14 dating

This half-life is about 5,700 years and means that every 5,700 years the amount of carbon-14 in a fossil is only one-half of what it was 5,700 years ago.

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.

Eventually, all the carbon-14 in the remains will disappear.

This principle applies equally to a person dying, a corn stalk being cut down, or to a soybean plant being pulled out of the ground.

When a plant stops assimilating carbon dioxide or when an animal or human being stops eating, the ingestion of carbon-14 also stops and the equilibrium is disrupted.
