Web29 apr. 2016 · Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha). The spontaneous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation. Web27 feb. 2024 · Ionising radiation is the term given to forms of radiation that are energetic enough to displace orbiting electrons from the atoms in the absorbing medium, thus forming positive ions. The process of ionisation is the principal means by which ionising radiations dissipate their energy in matter and thus may cause biomolecular damage.
