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.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.Living plants are active components of the overall food chain.Radiocarbon dating is applicable to biobased content measurements in manufactured products because they contain some combination of recently living materials and fossil materials.

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.When they stop living, they stop taking in carbon-14 from the air around them, and the amount of carbon-14 in the remains gradually disappears.A radiocarbon dating laboratory is able to measure the amount of carbon-14 remaining in a fossil.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.
