Decay Product

A radionuclide produced as a result of a parent radionuclide's decay. The decay products may be derived from their immediate predecessor, of through several other decays in a decay chain series. One example would be Radon Decay products where Ra-222 will decay to products including Polonium 218 (via alpha decay) and then Lead-214 (also alpha decay).
