Ionizing radiation (or ionising radiation), including nuclear radiation, ... X-rays normally have a lower energy than gamma rays, and an older convention was to define the boundary as a wavelength of 10 −11 m (or a photon energy of 100 keV). Meer weergeven 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. … Meer weergeven Ionizing radiation may be grouped as directly or indirectly ionizing. Any charged particle with mass can ionize atoms directly by fundamental interaction through the Coulomb force if it carries sufficient kinetic energy. Such particles include Meer weergeven Most adverse health effects of exposure to ionizing radiation may be grouped in two general categories: • deterministic effects (harmful tissue reactions) due in large part to killing or malfunction of cells following high doses from Meer weergeven Ionizing radiation is generated through nuclear reactions, nuclear decay, by very high temperature, or via acceleration of charged particles in electromagnetic fields. Natural … Meer weergeven Indirectly ionizing radiation is electrically neutral and does not interact strongly with matter, therefore the bulk of the ionization effects are … Meer weergeven Nuclear effects Neutron radiation, alpha radiation, and extremely energetic gamma (> ~20 MeV) can cause Meer weergeven Ionizing radiation has many industrial, military, and medical uses. Its usefulness must be balanced with its hazards, a compromise … Meer weergeven WebRadiation dose units are limited to ionizing radiation photons and ionizing particles (Tables 23.1, 23.2, and 23.3). Typically, ionizing radiation photons are defined in terms of energy expressed in multiples of the electron volt, keV (thousand electron volts) or MeV (million electron volts), rather than wavelength (λ) or frequency (Hz).
