A gamma ray or gamma radiation (symbol γ or ), is a penetrating electromagnetic radiation arising from the radioactive decay of atomic nuclei.It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium.
Gamma-rays are a form of electromagnetic radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Gamma-rays can be used to treat cancer, and gamma-ray ...
Gamma rays are electromagnetic radiation, like X-rays. The other two types of natural radioactivity are alpha and beta radiation, which are in the form of particles. Gamma rays are the most energetic form of electromagnetic radiation, with a very short wavelength of less than one-tenth of a nanometer. Gamma radiation is the product of ...
A stream of high-energy electromagnetic radiation given off by an atomic nucleus undergoing radioactive decay. Because the wavelengths of gamma rays are shorter than those of x-rays, gamma rays have greater energy and penetrating power than x-rays.
What Are Gamma Rays [/caption] In the universe there are kinds of energy and different ways it manifests itself. One common form is radiation. Radiation is the wave energy produced by ...
Side Effects of Gamma Radiation. Some of the possible problems with heavy exposure to gamma radiations include radiation sickness. This is also known as radiation poisoning. Some of the gamma radiation signs can be nausea, vomiting, bleeding, mouth sores, nausea, diarrhea and loss of hair.
What are gamma rays? A gamma ray is a packet of electromagnetic energy emitted by the nucleus of some radionuclides following radioactive decay.Gamma photons are the most energetic photons in the electromagnetic spectrum.Their emission commonly occurs within a fraction of a second after radioactive decay but sometimes occurs several hours later.
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. Physicists define gamma radiation as high-energy photons released by nuclear decay.
What is gamma radiation used for? Common applications for gamma processing (treatment) include the sterilizing (killing of bacteria) of medical devices, microbial reduction of foods, cosmetics and their packaging, and the deinfestation of agricultural products. Follow this link to find a list of products commonly treated with irradiation.
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 gamma-ray radiation having wavelengths that are generally shorter than a few tenths of an angstrom (10 −10 metre) and gamma-ray ...
