Radiocarbon dating services uk

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.

Radiocarbon immediately reacts with oxygen in the air to form carbon dioxide (CO2).

This carbon dioxide rapidly mixes throughout the atmosphere, where at ground level it is taken in by plants during photosynthesis.

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.

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.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.Call (305) 662-7760 or fill out our sample form today if you’re ready to send samples for testing.
