Managing exposure to ionizing radiation - Canada.ca
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 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 … 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 … Meer weergeven 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 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 Web9 apr. 2024 · Examples of non-ionizing radiation are ultraviolet, visible, infrared, microwave, and radio waves. Measure the exposure The second step is to measure the exposure level of your workers to the ... Web12 aug. 2024 · Demonstration B shows that ionizing radiation can change the structure of an atom by breaking chemical bonds in molecules or removing tightly bound electrons from atoms and creating charged molecules or atoms (ions).
