This transformation is accomplished by the emission of particles such as electrons (known as beta decay) or alpha particles.While the moment in time at which a particular nucleus decays is random, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life, usually given in units of years when discussing dating techniques.After one half-life has elapsed, one half of the atoms of the substance in question will have decayed.For a single element, these atoms are called isotopes.Radiometric dating is a technique used to date materials based on a knowledge of the decay rates of naturally occurring isotopes, and the current abundances.
