WebIonising radiation: risks from exposure. This report (HPA-RPD-066) provides a brief commentary on the basis for current radiation risk estimates. From: Public Health … Ionizing radiation is used in a wide variety of fields such as medicine, nuclear power, research, and industrial manufacturing, but presents a health hazard if proper measures against excessive exposure are not taken. Exposure to ionizing radiation causes cell damage to living tissue and organ damage. 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 … 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 … Meer weergeven Most adverse health effects of exposure to ionizing radiation may be grouped in two general categories: • deterministic effects (harmful tissue reactions) … Meer weergeven Ionizing radiation is generated through nuclear reactions, nuclear decay, by very high temperature, or via acceleration of charged … Meer weergeven
