A relatively short-range dating technique is based on the decay of uranium into thorium, a substance with a half-life of about 80, years. For example, how do we know that the Iceman, whose frozen body was chipped out of glacial ice inis 5, years old? Strontium is a stable element; it does not undergo further radioactive decay.

Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. The correct relation can obtained by rearranging the equation given at the beginning of this post:
