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.

檢視所有 Wikipediahttps://en.wikipedia.org/wiki/Ionizing_radiationIonizing 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

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
https://zh.wikipedia.org/zh-tw/游離輻射游離輻射（英語：ionizing radiation）又稱電離輻射 ，是指波長短、頻率高、能量高的射線（粒子或波的雙重形式）。輻射可分為游離輻射和非游離輻射，游離輻射可以從原子或分子裡面電離過程（Ionization）中作用出至少一個電子。反之，非游離輻射則不行。游離能力，決定於射線（粒子或波）所帶的能量，而不是射線的數量。如果射線沒有帶有足夠游離能量的話，大量的射線並不能夠導 …

Effects of ionizing radiation in spaceflight - Wikipedia
https://en.wikipedia.org/wiki/Effects_of_ionizing_radiation_in_spaceflight- While in space, astronauts are exposed to radiation which is mostly composed of high-energy protons, helium nuclei (alpha particles), and high-atomic-number ions (HZE ions), as well as secondary radiationfrom nuclear reactions from spacecraft parts or tissue. The ionization patterns in molecules, cells, tissues and the resulting biological effects ...

Ionization occurs when an electron is stripped (or "knocked out") from an electron shell of the atom, which leaves the atom with a net positive charge.
