It was immediately blasted with gamma-rays from blazar 3C454.3 - visible in the lower left quadrant of the telescope's first map of the sky. "It's a good example of the kind of things that are in store for us," says project scientist Steven Ritz of NASA's Goddard Space Flight ...
Gamma rays are produced by the nuclei of isotopes undergoing disintegration because of their basic instability. Isotopes are varieties of the same chemical elements but have different atomic weights. A parent element and its isotopes both have an identical number of protons in their nuclei but a di...
The word gamma occurs often in everyday life, in terms like gamma rays, the star called Gamma Velorum, and gamma-GTP. In computer image processing, the term generally refers to the brightness of intermediate tones (gray). Let's discuss gamma in a little more detail. In a PC environment,...

We selected a measurement time of 300 s to obtain stable spectra. When in direct contact with an outcrop, the instrument collects the gamma rays emitted from 15 to 25 cm depth (depending upon density) within a 1 m circular disc. The instrument applies stripping and background corrections on...
Gamma rays are electromagnetic radiation, like X-rays, except even more energetic. They have enough energy to ionize matter and can damage or destroy living cells, which is of course why they are useful for sterilization. The source of gamma rays in a gamma irradiator is Cobalt-60. Cobalt-...

Within a year, BATSE was detecting around one GRB per day, and the spacecraft went on to produce the first-ever all-sky survey in gamma-rays. This revealed that GRB sources are distributed almost evenly (or "homogeneously") across the universe, according to the Swinburne Centre for ...
In fact, they account for the majority of galactic sources emitting TeV Gamma-Rays; further, a number of unidentified gamma-ray sources are likely to be associated with unobserved pulsars [7]. Finally, very recent measurements by the LHAASO telescope [8] might indicate that PWNe are also the...
The radiological monitoring of radwaste must be based on the measurement of gamma-rays and neutrons because these are penetrating and thus more easily detectable out of the drums. Due to the foreseen mass deployment, the sensors must be reasonably low-cost and configurable in a modular and scala...
