Aug 10, 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. On Earth, gamma waves are generated by nuclear explosions, lightning, and ...

Nov 3, 2024 · gamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. The commonly accepted definitions of the gamma-ray and X-ray regions of the electromagnetic spectrum include some wavelength overlap, with ...
Dec 28, 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. Because of a quantum ...
One of the most common gamma ray emitting isotopes used in diagnostic nuclear medicine, technetium-99m, produces gamma radiation of the same energy (140 keV) as that produced by diagnostic X-ray machines, but of significantly lower energy than therapeutic photons from linear particle accelerators. In the medical community today, the convention that radiation produced by nuclear decay is the ...
Nov 18, 2014 · Processes that Create Cosmic Gamma Rays. There are several physical processes that generate cosmic gamma rays: A high-energy particle can collide with another particle. A particle can collide and annihilate with its anti-particle. An element can undergo radioactive decay. A charged particle can be accelerated.
Apr 5, 2023 · Storm clouds produce some of the highest-energy light naturally made on Earth: terrestrial gamma-ray flashes. The tropical disturbance that would later become Hurricane Julio in 2014 produced four flashes within 100 minutes, with a fifth the next day. NASA's Goddard Space Flight Center. Fermi has also spotted terrestrial gamma-ray flashes ...
Nov 29, 2018 · Gamma rays are produced primarily by four different nuclear reactions: fusion, fission, alpha decay and gamma decay. Nuclear fusion is the reaction that powers the sun and stars. It occurs in a ...
