Carbon dating fossil
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.
Recently living materials (the biobased component) have Carbon-14 in them while fossil materials (derived from petroleum) no longer have this weakly radioactive carbon isotope.
Thus all the carbon-14 in the product comes from the biobased component.
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.
From that time forward, the only process at work in the body is radioactive decay.
After 50,000 years, a fossil won’t have any radiocarbon left in it.
Radiocarbon dating uses carbon-14 to determine the last time something (or someone) was alive.Radiocarbon, or carbon-14 (also written as C), is an isotope of carbon that is unstable and weakly radioactive.Carbon-14 is present in all living things in minute amounts.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.It also means that if a dead plant has 50% as much carbon-14 in it than in a living plant, the dead plant was alive about 5,700 years ago.
