ionizing radiation wikipedia - EAS
- Ionizing radiation is a process in physics where something sends out particles or waves that can ionize an atom or molecule through atomic interactions. The strength of ionizing radiation depends on the energy of the individual particles or waves, and not a function of the number of particles or waves present.simple.wikipedia.org/wiki/Ionizing_radiation

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. The particles generally travel at a speed that is 99% of the speed of light, … 查看更多內容
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 … 查看更多內容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 查看更多內容Most adverse health effects of exposure to ionizing radiation may be grouped in two general categories:
• deterministic effects (harmful tissue reactions) due … 查看更多內容Ionizing radiation is generated through nuclear reactions, nuclear decay, by very high temperature, or via acceleration of charged particles in electromagnetic fields. Natural sources … 查看更多內容
Nuclear effects
Neutron radiation, alpha radiation, and extremely energetic gamma (> ~20 MeV) can cause 查看更多內容Ionizing radiation has many industrial, military, and medical uses. Its usefulness must be balanced with its hazards, a compromise that has shifted over time. For example, at one time, assistants in shoe shops used X-rays to check a child's shoe size, … 查看更多內容
There are three standard ways to limit exposure:
1. Time: For people exposed to radiation in addition to natural background radiation, limiting or minimizing the exposure time will reduce the dose from the radiation source. 查看更多內容CC-BY-SA 授權下的維基百科文字 游離輻射 - 維基百科,自由的百科全書
