What are gamma rays?

Gamma-rays are a form of electromagnetic radiation. They can be used to treat cancer, and gamma-ray bursts are studied by astronomers. read more

A gamma ray or gamma radiation (symbol γ or ), is penetrating electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of photons in the highest observed range of photon energy. read more

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 bursts are studied by astronomers. read more

Gamma-ray spectroscopy, involving the precise measurement of gamma-ray photon energies emitted by different nuclei, can establish nuclear energy-level structures and allows for the identification of trace radioactive elements through their gamma-ray emissions. read more
