Over time, more and more fluorine incorporates itself into the bone. The older the pottery, the brighter the light that will be emitted. A particular isotope of a particular element is called a nuclide. The curves are then compared with one another, and from this the relative ages of the styles are determined. Dendrochronology has a range of one to 10, years or more. Older materials can be dated using zircon , apatite , titanite , epidote and garnet which have a variable amount of uranium content. The dates when areas of North America were first settled by immigrants can be determined to within a few years by looking for the introduction of ragweed pollen. Once an artefact is compared to its known development date then whenever that item reappears in the archaeological record, of that or any other site, it can quickly be dated. When the organism dies, however, its body stops incorporating new carbon. Fossils are important for working out the relative ages of sedimentary rocks. Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element is converted into another radioactive isotope or non-radioactive product at a regular rate.

    When an organism dies, it ceases to take in new carbon, and the existing isotope decays with a characteristic half-life years. Before the advent of absolute dating methods, nearly all dating was relative.
