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.When a radiocarbon dating lab doesn’t see any carbon-14 in a fossil, it knows the fossil is more than 50,000 years old.Petroleum and dinosaur bones are examples of fossil materials that no longer have carbon-14 remaining in them.Animals eat plants and/or other animals; humans eat plants and animals.

A radiocarbon dating laboratory is able to measure the amount of carbon-14 remaining in a fossil.Radiocarbon dating is applicable to biobased content measurements in manufactured products because they contain some combination of recently living materials and fossil materials.The standard developed for this purpose is called ASTM D6866.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.This process is constantly ongoing, so that at any point in time the amount of carbon-14 in living plants is the same as the amount of carbon-14 in the air around them.
