A gamma ray, also known as gamma radiation (symbol γ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays.
A gamma ray is electromagnetic radiation of the shortest wavelength and highest energy. Gamma-ray radiation has wavelengths generally smaller than a few tenths of an angstrom (10 −10 meter), and gamma-ray photons have energies greater than tens of thousands of electron volts.
- Gamma rays are produced during the disintegration of radioactive atomic nuclei and the decay of certain subatomic particles. Gamma rays are also pr...
- The term gamma ray was coined by British physicist Ernest Rutherford in 1903, following early studies of the emissions of radioactive nuclei.
- Medical applications of gamma rays include the imaging technique of positron emission tomography (PET) and radiation therapies to treat cancerous t...
10 ago 2016 · Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.

14 mag 2024 · Gamma rays or gamma radiation are a form of electromagnetic radiation with extremely high frequency and energy. They are a significant topic of study in fields such as nuclear physics, astrophysics, and medical science due to their unique properties and diverse applications.
28 dic 2022 · Gamma rays are high-energy photons produced by some of the most violent events in the universe. Photons of light are massless particles that are essentially packets of energy....
What are Gamma Rays? Gamma rays are a form of light. All light travels in waves and is classified according to its wavelength, the distance between its waves. The universe produces a broad range of light, only a fraction of which is visible to our eyes.
5 ago 2021 · Gamma radiation (gamma rays) refers to the part of the electromagnetic spectrum with the most energy and shortest wavelength. Astrophysicists define gamma radiation as any radiation with an energy above 100 keV.
