Furthermore, Parentium and Daughterium are so different in chemical properties that they don't otherwise occur together.If there were such a pair of isotopes, radiometric dating would be very simple.

In 1905, shortly after the discovery of radioactivity, the American chemist Bertram Boltwood suggested that lead is one of the disintegration products of uranium, in which case the older a uranium-bearing mineral the greater should be its proportional part of lead.

Analyzing specimens whose relative geologic ages were known, Boltwood found that the ratio of lead to uranium did indeed increase...

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.

This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Some do not change with time and form stable isotopes (i.e.

Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces.
