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.
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.
- A gamma ray is electromagnetic radiation of the shortest wavelength and highest energy. Gamma-ray radiation has wavelengths generally smaller than...
- 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.
