Lowest ionizing radiation
 Radiation - Overview)
WebThe simplest ultimate effect of absorption of radiation is heating. It can be argued that, for ionizing radiation of low linear energy transfer, the heating effect is negligible. A spur created by such low-LET radiation is a small spherical region in which the energy deposit is localized in isolation. The temperature rise, ΔT, of the spur above the surrounding … The lowest ionization energy of any element is 3.89 eV, for caesium. However, US Federal Communications Commission material defines ionizing radiation as that with a photon energy greater than 10 eV (equivalent to a far ultraviolet wavelength of 124 nanometers). 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 Meer weergeven Nuclear effects Neutron radiation, alpha radiation, and extremely energetic gamma (> ~20 MeV) can cause nuclear transmutation and induced radioactivity Meer weergeven Ionizing radiation has many industrial, military, and medical uses. Its usefulness must be balanced with its hazards, a compromise … Meer weergeven 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 … 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.
