Radioactive decay, also known as nuclear decay or radioactivity, is a random process by which an unstable atomic nucleus loses its energy by emission of radiation or particle. A material containing unstable nuclei is considered radioactive.
Radioactive decay occurs when a nucleus contains an imbalance in the number of protons and neutrons, making it unstable. To achieve stability, the nucleus releases energy and particles, which can include alpha (α) particles, beta (β) particles, and gamma (γ) rays. Each type of emission a...
Nuclear decay, also referred to as nuclear radiation, radioactivity, or radioactive decay, occurs when energy in the form of radiation is lost from an atom because its nucleus is unstable. Nuclear decay can occur both naturally and through intentional human activities. Natural sources of nuclear ...

How does radioactive decay occur? Radioactive decay occurs when an atom's nucleus has too much energy, making it unstable. To reach a more stable state, the nucleus will emit particles or energy until it reaches a lower energy state. ...

Radioactive Decay When these nuclei lose energy and break apart, decay occurs. Radioactive decay releases energy from the nucleus as radiation. Radioactive atoms release energy until they become stable, often as different atoms. An element may have only certain isotopes that are radioactive. These...
