Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.

The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

The activity of 1890 wood is corrected for radioactive decay to 1950.

Additionally, elements may exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.Radiometric techniques are one method of absolute dating and, for example, counting tree rings is another form of absolute dating.Any technique that assigns a certain age or date is a form of absolute dating.Relative dating simply says one is older than the other but no age is specified.Tools in the category of radiometric dating are based on the known rates of radioactive decay of isotopes and this allow some samples to be assigned a certain age rdiometric within some radiomwtric.
