- Electrons orbit the nucleus and are arranged in layers called shells. Removing one of the outer electrons from an atom emits energy, usually in the form of gamma rays. This phenomenon can is called ionizing radiation.

Jul 27, 2023 · 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.
Gamma rays, X-rays, and the higher energy ultraviolet part of the electromagnetic spectrum are ionizing radiation, whereas the lower energy ultraviolet, visible light, nearly all types of laser light, infrared, microwaves, and radio waves are non-ionizing radiation.
In astrophysics, gamma rays are conventionally defined as having photon energies above 100 keV and are the subject of gamma-ray astronomy, while radiation below 100 keV is classified as X-rays and is the subject of X-ray astronomy. Gamma rays are ionizing radiation and are thus hazardous to life.
Oct 26, 2020 · Energy emitted from a source is generally referred to as radiation. Examples include heat or light from the sun, microwaves from an oven, X rays from an X-ray tube and gamma rays from radioactive elements. Ionizing radiation can remove electrons from the atoms, i.e. it can ionize atoms.

Nov 4, 2024 · Ionizing radiation includes the more energetic end of the electromagnetic spectrum (X-rays and gamma rays) and subatomic particles, such as electrons, neutrons, and alpha particles (helium nuclei each comprising two protons and two neutrons).
Feb 19, 2024 · 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.

May 14, 2024 · When gamma rays encounter matter, they interact primarily through three processes: Photoelectric Effect: Gamma rays can eject electrons from atoms and cause ionization. Compton Scattering: Gamma rays transfer part of their energy to electrons, causing the electrons to scatter and the gamma rays to change direction and lose energy.
