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, 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 - 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]
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.
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, …
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.
What is Radiation? | IAEA - International Atomic Energy Agency
2023年1月25日 · Ionizing radiation is a type of radiation of such energy that it can detach electrons from atoms or molecules, which causes changes at the atomic level when interacting with matter including living organisms.
Radiation Basics | US EPA - U.S. Environmental Protection Agency
2024年10月1日 · Ionizing radiation has so much energy it can knock electrons out of atoms, a process known as ionization. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. Ionizing radiation comes from x-ray machines, cosmic particles from outer space and radioactive elements. Radioactive ...
What Is Ionizing Radiation? | NRC.gov
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.
