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.

Other short-lived isotopes are thus seen only as extinct radionuclides, whose former existence is inferred now from a superabundance of their stable decay products.

Examples of extinct radionuclides include iodine-129 (the first to be noted in 1960, and inferred from excess xenon-129 concentrations in meteorites, in the xenon-iodine dating system), aluminium-26 (also inferred from extra magnesium-26 found in meteorites), and iron-60.

Another example of short-lived extinct radionuclide dating is the 26Al Open Access Articles- Top Results for Radiometric dating. After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a “daughter” nuclide or .Another example of short-lived extinct radionuclide dating is the 26 Al – 26 Mg To Kill a Mockingbird Whats the themes of To Kill a Mockingbird? In many cases, the daughter nuclide itself is radioactive, resulting in a , eventually ending with the formation of a stable (nonradioactive) daughter nuclide; each step in such a chain is characterized by a distinct half-life.An extinct radionuclide is one that scientists believe was formed by primordial processes, such as stellar nucleogenesis in the supernova(s) that contributed radioisotopes to the early solar system, about 4.6 billion years ago.
