Ionizing radiation - Wikipedia
Ionizing radiation (US, ionising radiation in the UK), including nuclear radiation, consists of subatomic particles or electromagnetic waves that have sufficient energy to ionize atoms or molecules by detaching electrons from them. [1]
Ionization - Wikipedia
Ionization (or ionisation specifically in Britain, Ireland, Australia and New Zealand) is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion.
Ionizing radiation | Definition, Sources, Types, Effects, & Facts ...
2024年11月4日 · ionizing radiation, flow of energy in the form of atomic and subatomic particles or electromagnetic waves that is capable of freeing electrons from an atom, causing the atom to become charged (or ionized).
About Ionizing Radiation | Radiation and Your Health | CDC
2024年2月19日 · Ionizing radiation is a powerful form of energy with medical applications such as diagnostic testing. At high enough doses, it can alter your body's cells and DNA. Unlike some non-ionizing radiation, it can cause serious harm or cancer with enough exposure. Radiation exists all around us and is in two forms: ionizing and non-ionizing radiation.
Ionizing radiation and health effects - World Health Organization …
2023年7月27日 · Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha). The spontaneous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation.
Ionizing Radiation - Definition, Examples, Types, Sources & Quiz
2017年5月18日 · Ionizing radiation gives off energy by knocking electrons off atoms, which causes the atoms to have a charge. Another term for a charged particle is an ion. The charges on the atomic particles make ionizing radiation unstable and reactive.
Difference Between Ionizing and Non-Ionizing Radiation
2021年4月14日 · Ionizing radiation includes subatomic particles and the high energy, short-wavelength portion of the electromagnetic spectrum. Non-ionizing radiation include the visible spectrum and the low energy, long-wavelength part of the spectrum beyond visible light.
Ionization | Definition, Examples, & Facts | Britannica
ionization, in chemistry and physics, any process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) through gaining or losing electrons. Ionization is one of the principal ways that radiation, such as charged particles and X rays, transfers its energy to matter.
Radiation: Ionizing radiation - World Health Organization (WHO)
2020年10月26日 · Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become charged or ionized. Here we are concerned with only one type of radiation, ionizing radiation, …
What Is Ionizing Radiation? | NRC.gov
2020年3月19日 · Ionizing radiation is radiation with enough energy to create ion pairs in atoms. It is ionizing radiation that is of particular interest to the NRC because of its potential to cause health effects. To help you visualize this, think again about Bohr's model.
