Information about Decay Energy
The decay energy is the energy released by a nuclear decay.
The difference between the mass of the reactants and the mass of products is often written as Q:
Decay energy is usually quoted in terms of the energy units MeV (million electronvolts) or KeV (thousand electronvolts).
Types of radioactive decay include

The difference between the mass of the reactants and the mass of products is often written as Q:
- Q = (mass of reactants) - (mass of products)
Decay energy is usually quoted in terms of the energy units MeV (million electronvolts) or KeV (thousand electronvolts).
Types of radioactive decay include
- gamma radiation
- beta decay (decay energy is divided between the emitted electron and the invisible neutrino which is emitted at the same time)
- alpha decay

energy (from the Greek ενεργός, energos, "active, working")[1] is a scalar physical quantity that is a property of objects and systems of objects which is conserved by nature.

Radioactive decay is the process in which an unstable atomic nucleus loses energy by emitting radiation in the form of particles or electromagnetic waves. This decay, or loss of energy, results in an atom of one type, called the parent nuclide

Mass is a fundamental concept in physics, roughly corresponding to the intuitive idea of "how much matter there is in an object". Mass is a central concept of classical mechanics and related subjects, and there are several definitions of mass within the framework of relativistic

A reactant or reagent is a substance consumed during a chemical reaction.[1] Solvents and catalysts, although they are involved in the reaction, are usually not referred to as reactants.

A product is a substance that forms as a result of a chemical reaction. While the end product of some chemical reactions may be the result of a relatively rapid reaction, nanoseconds to seconds, chemical equilibria in complex systems may require years or even centuries to be

The electronvolt (symbol eV) is a unit of energy. In theoretical physics, where distinctions between mass and energy are not concrete, it is often used also as a unit of mass (AAAS Science journal, 2006).

Gamma rays or gamma-ray (denoted as γ) are forms of electromagnetic radiation (EMR) or light emissions of a specific frequency produced from sub-atomic particle interaction, such as electron-positron annihilation and..... Click the link for more information.
beta decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted. In the case of electron emission, it is referred to as "beta minus" (β−), while in the case of a positron emission as "beta plus" (β+).

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (two protons and two neutrons bound together into a particle identical to a helium nucleus) and transforms (or 'decays') into an atom with a mass number 4 less and atomic number 2 less.
