Over 60 further radionuclides are detectable in nature, either as daughters of these, or through natural production on Earth by cosmic radiation.

More than 2400 radionuclides have half-lives less than 60 minutes.

However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.

As soon as they come to rest, they combine with an electron to form two -ray photons in a matter-antimatter annihilation reaction.-decay are often obtained in an excited state.

The range of the half-lives of radioactive atoms have no known limits and span a time range of over 55 orders of magnitude.

Radionuclides occur naturally and are artificially produced in nuclear reactors, cyclotrons, particle accelerators or radionuclide generators.

Once we understand what we actually need to do we can apply the same principles to radioactive dating, and see if the methods do what they are claimed to do.
