Radioactivity | Definition, Types, Applications, & Facts | Britannica
Radioactivity, property exhibited by certain types of matter of emitting energy and subatomic particles spontaneously. It is, in essence, an attribute of individual atomic nuclei.
Radioactive decay - Wikipedia
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.
Radioactivity: Definition, Types, Formula, and Applications
Radioactivity occurs when an atom has an excess of energy, mass, or both, making its nucleus unstable. To reach a lower, more stable energy level, it releases energy in the form of radiation. This radiation can be emitted as particles or electromagnetic waves, depending on the nature of the decay.
What Is Radioactivity? - Energy.gov
As its name implies, radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it "wants" to give up some energy in order to shift to a more stable configuration.
Radioactivity and the Types of Radioactive Decay
Radioactivity is the spontaneous emission of ionizing radiation from nuclear decay and reactions. The three main types of radioactive decay are alpha, beta, and gamma decay, but there are other nuclear reactions responsible for radioactivity.

This process is known as radioactivity and the energy that's released is radiation. After an atom expels energy from the nucleus, the composition of the nucleus changes, and we are left with a different element that is more stable.
What Is Radioactivity? (with pictures) - AllTheScience
Radioactivity is the process whereby unstable atomic nuclei release energetic subatomic particles or electromagnetic radiation (EMR). This phenomenon can cause one element to turn into another and is partly responsible for the heat of the Earth’s core.
Radioactivity | Understanding Its Basics & Effects
Radioactivity is a natural phenomenon involving the decay of unstable atomic nuclei, which release energy in the form of radiation. This process helps us understand atomic structures and has applications ranging from medical treatments to energy production.

This page offers a comprehensive overview of radioactivity, detailing atomic structure and the different types of radioactive emissions: alpha particles, beta particles, and gamma rays.
Radiation in Everyday Life - International Atomic Energy Agency
Radioactivity is the term used to describe disintegration of atoms. The atom can be characterized by the number of protons in the nucleus. Some natural elements are unstable. Therefore, their nuclei disintegrate or decay, thus releasing energy in the form of radiation.
