Ionising radiation primary beam
WebIonising radiation occurs as either electromagnetic rays (such as X-rays and gamma rays) or particles (such as alpha and beta particles). It occurs naturally (eg from the radioactive decay of... 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

Radiotherapy is aimed at destroying cancerous changes using ionising radiation (IR); however, in some cases, solid epithelial breast tumours are observed to be resistant to the apoptosis that is induced by IR.
WebMagnetic Resonance Imaging (MRI) is a groundbreaking non-ionising imaging modality that revolutionised the field of diagnostic medicine. Developed in the 1970s, MRI uses a combination of powerful magnetic fields, radiofrequency pulses, and sophisticated computer algorithms to generate detailed images of the body’s internal structures.
