Ionizing radiation - Wikipedia

Directly ionizing radiation [ edit] Alpha particles [ edit]. Alpha particles consist of two protons and two neutrons bound together into a particle... Beta particles [ edit]. Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of... Positrons and other types of ... See more Ionizing radiation (or ionising radiation), including nuclear radiation, consists of subatomic particles or electromagnetic waves that have sufficient energy to ionize atoms or molecules by detaching electrons from them. Some … See more Nuclear effects Neutron radiation, alpha radiation, and extremely energetic gamma (> ~20 MeV) can cause nuclear transmutation and induced radioactivity. The relevant mechanisms are neutron activation, alpha absorption, and See more Ionizing radiation has many industrial, military, and medical uses. Its usefulness must be balanced with its hazards, a compromise that … See more Ionizing radiation is generated through nuclear reactions, nuclear decay, by very high temperature, or via acceleration of charged particles in … See more Ionizing radiation may be grouped as directly or indirectly ionizing. Any charged particle with mass can ionize atoms directly … See more Indirectly ionizing radiation is electrically neutral and does not interact strongly with matter, therefore the bulk of the ionization effects are due to secondary ionization. Photon radiation Even though photons are electrically neutral, they can … See more Most adverse health effects of exposure to ionizing radiation may be grouped in two general categories: • deterministic effects (harmful tissue reactions) due in … See more WebApr 29, 2016 · Ionizing radiation is a type of energy released by atoms in the form of electromagnetic waves or particles.
