Measuring the amount of radioactive carbon remaining makes it possible to work out how old the artifact is, whether it's a fossilized skeleton or a magnificent piece of artwork. Plants take up atmospheric carbon dioxide by photosynthesisand are eaten by animals, so every living thing is constantly exchanging carbon with its environment as long as it lives. In addition, samples need to be thoroughly cleaned to remove carbon contamination from glues and soil before dating.
