WebCarbon dating is a technique. The technique is, in turn, based on a series of theories. It relies, for example, on ideas like consistent half-lives for radioactive isotopes and a premise that cosmic radiation produces radioactive carbon from nitrogen in the upper atmosphere at a more or less consistent rate. WebRemoving the carbonates also destroys the calcium hydroxyapatite, and so it is usual to date bone using the remaining protein fraction after washing away the calcium hydroxyapatite and contaminating carbonates. This protein component is called collagen.
