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:

Q = (mass of reactants) - (mass of products)

This can be expressed as energy by Albert Einstein's famous formula E=mc².

Types of decay energy include

• gamma radiation
• beta decay
• alpha decay
