English: A diagram illustrating the radioactive decay chains of the non-synthetic elements. The four decay chains shown are thorium (in blue); radium (in red); actinium (in green); and; neptunium (in purple).
The decay scheme of a radioactive substance is a graphical presentation of all the transitions occurring in a decay, and of their relationships. Examples are shown below. It is useful to think of the decay scheme as placed in a coordinate system, where the vertical axis is energy, increasing from bottom to top, and the horizontal axis is the proton number, increasing from left to right.

Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay.
The decay scheme of 60 Co and 60m Co.. The diagram shows a simplified decay scheme of 60 Co and 60m Co. The main β-decay transitions are shown. The probability for population of the middle energy level of 2.1 MeV by β-decay is 0.0022%, with a maximum energy of 665.26 keV.
The 238 U decay chain contributes six electron anti-neutrinos per 238 U nucleus (one per beta decay), resulting in a large detectable geoneutrino signal when decays occur within the Earth. [3] The decay of 238 U to daughter isotopes is extensively used in radiometric dating, particularly for material older than approximately 1 million years.
English: Diagram of the thorium decay chain from lead-212 to lead-208. Each parent nuclide spontaneously decays into a daughter nuclide (the decay product) via an α decay or a β − decay. Note that bismuth-212 can either decay into polonium-212 or thallium-208.
