{wiki=Gamma-Ray_Imaging_Spectrometer}
The Gamma-Ray Imaging Spectrometer (GRIS) is a scientific instrument designed to detect and analyze gamma-ray emissions from various sources, such as astronomical objects, planetary bodies, and terrestrial environments. These emissions can provide valuable information about the composition, structure, and processes occurring in the observed phenomena. Gamma rays are electromagnetic radiation emitted by radioactive materials and certain cosmic events; they have very high energy.
