Living things are in equilibrium with the atmosphere, and the radioactive carbon dioxide is absorbed and used by plants. The half-life is so short years that this method can only be used on materials less than 70, years old. We define the rate of this radioactive decay in half-lives. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock. Since the rock formation contains both types of fossils the ago of the rock formation must be in the overlapping date range of to million years. At death, Carbon 14 exchange ceases and any Carbon 14 in the tissues of the organism begins to decay to Nitrogen 14, and is not replenished by new C Radioactive isotopes don't tell much about the age of sedimentary rocks or fossils. Studying the layers of rock or strata can also be useful. The radioactive minerals in sedimentary rocks are derived from the weathering of igneous rocks.
