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 el
Precision linear and two-dimensional scintillation crystal arrays for x-ray and gamma-ray imaging applications The continuing demand for greater resolution and real-time imaging and the availability of improved, position-sensitive light sensors such as a-Si arrays h... DJ Krus,WP Novak,L Perna -...
Gamma-Ray Sources In subject area: Physics and Astronomy Gamma-ray sources refer to regions in space emitting high-energy gamma radiation, often discovered through satellite missions. Some of these sources remain unidentified and can be categorized based on their location, spectral properties, and ass...

The mean free path is the average distance the gamma ray travels through the material before it undergoes some sort of interaction, such as Compton scattering or the photoelectric effect. From: Handbook of Radioactivity Analysis: Volume 2 (Fourth Edition), 2020 ...
The camera contains a scintillation crystal, so gamma-rays impinging on zones of the crystal produce spots of light with coordinates (x,y). The spots of light are picked up by a bundle of photomultipliers, which feed corresp. signals to a computer. The computer feeds the coordinates (x,y)...
The low sampling rate ADCs connected to the stilbene-SiPM array module result in a compact instrument with high sensitivity that provides a gamma-ray image of aCs source, producing 6.4 μR/h at 1m, in less than 69s. A neutron image for a 3.5×10n/sCf source can also be obtained in ...
Gamma-ray astronomy has been one of the prime scientific research fields of the Max-Planck Institute for Extraterrestrial Physics (MPE) from its beginning. Over the years, the entire gamma-ray energy range accessible from space was explored. The purpose of this review article is to summarise the...
Are gamma rays light? What is the wavelength of gamma rays? What is alpha radiation? What causes gamma ray bursts? What are cosmic rays used for? What is beta ionizing radiation and their properties? What is the charge of a gamma ray?
Researchers just created the world's first image of a terrestrial gamma-ray burst, one of the most mysterious and energetic events on Earth.
