The Half-Life Isotopes decay at a constant rate known as the half-life. Thus an igneous or metamorphic rock or melt, which is slowly cooling, does not begin to exhibit measurable radioactive decay until it cools below the closure temperature. Creationists claim that argon escape renders age determinations invalid. The uranium content of the material can then be calculated from the number of tracks and the neutron flux. Potassium-Argon dating: At the end of the first half life, only half of the radioactive element remains, and therefore the production rate of the element formed by radioactive decay will be only half of what it was at the beginning. These neutrons can become unstable, and when they do, they release energy and undergo decay. See Carbon 14 Dating in this web site. However, local eruptions of volcanoes or other events that give off large amounts of carbon dioxide can reduce local concentrations of carbon and give inaccurate dates. Potassium has a half-life of 1. Carbon, uranium, and potassium are just a few examples of elements used in radioactive dating. Con radioactive dating can only be used to date fossils older than approximately 50, years old. So in order to date most older fossils, scientists look for layers of igneous rock or volcanic ash above and below the fossil. What is radioactive dating
