Radioactive decay (also known as nuclear decay, radioactivity or nuclear radiation) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, or a gamma ray or electron in the case of internal conversion. A material containing such unstable nuclei is considered radioactive. Certain highly excited short-lived nuclear states can decay through neutron emission, or more rarely, proton emission.

Radioactive decay is a process in which there is the emission of energy in the form of ions from a nucleus of a particle.

What are radioactive particles?

Radioactive particles are alpha, beta, neutrons, and electromagnetic waves such as gamma rays. These particles are emitted by the elements like uranium, plutonium, etc.

Radioactive decay is also known as nuclear decay, radioactivity, or nuclear radiation. A substance with such unstable nuclei is regarded as radioactive. Neutron emission, or less frequent proton emission, can be used to decay some highly excited short-lived nuclear states.

According to quantum theory, it is impossible to anticipate whether a certain atom will experience nuclear disintegration or radioactive decay. Examples are Alpha decay, beta decay, double proton emission, proton emission, etc.

Thus, the process of radioactive decay involves the discharge of energy from a particle's nucleus in the form of ions.
