Gamma ray - Wikipedia
Gamma rays are ionizing radiation and are thus hazardous to life. They can cause DNA mutations, cancer and tumors, and at high doses burns and radiation sickness. Due to their high penetration power, they can damage bone marrow and internal organs.
Gamma ray | Definition, Uses, Wavelength, Production, Examples, & Facts ...
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. It includes some overlap with X-rays in the electromagnetic spectrum.
Gamma Rays or Gamma Radiation - Definition and Properties
Learn about gamma rays or gamma radiation. Discover their properties, sources, health hazards, detection, and uses.
Gamma Rays - NASA Science
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.
Gamma rays: Everything you need to know | Space
Gamma rays are high-energy photons produced by some of the most violent events in the universe. We explore this powerful radiation in more detail here.
What Are X-rays and Gamma Rays? - American Cancer Society
Because X-rays and gamma rays have the same properties and health effects, they are grouped together here. Both x-rays and gamma rays are forms of high-frequency (high-energy) ionizing radiation, which means they have enough energy to remove an electron from (ionize) an atom or molecule.
Gamma Decay: Sources, Equation, Properties, & Applications
Gamma decay (denoted by the Greek symbol γ) is a type of radioactive decay that occurs when an unstable atomic nucleus releases excess energy in the form of gamma rays. Gamma rays are a form of high-energy electromagnetic radiation, similar to X-rays but with even greater energy.
What are the properties of gamma rays? Definition and uses
Gamma radiation is one of the most dangerous types of very high-frequency radiation for humans, as are all ionizing radiation. The danger stems from the fact that they are high-energy waves capable of producing molecular changes and damaging the molecules that make up cells.
ESA - Why do we observe gamma rays?
These are produced by spectacular events in the Universe such as stars exploding, matter falling into black holes and celestial objects colliding. By collecting gamma rays, astronomers are able to see these violent events and can judge exactly how they shape the Universe.
Gamma Radiation | Types, Properties & Uses
Gamma radiation, denoted by the Greek letter gamma (γ), is a form of electromagnetic radiation that is at the high-energy end of the electromagnetic spectrum. It is characterized by having the shortest wavelength and highest energy among the various types of electromagnetic waves.
