Radioactive decay and radiometric dating 1

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.

radioactive decay also known as nuclear decay radioactivity or nuclear radiation is the process by which an unstable atomic nucleus loses energy in terms of mass in its rest frame by emitting radiation such as an alpha particle beta particle with neutrino or only a neutrino in the case of electron capture or a gamma ray or electron in the case of internal conversion.
