Natural sources of gamma rays on Earth include gamma decay from naturally occurring radioisotopes such as potassium-40, and also as a secondary radiation from various atmospheric interactions with cosmic ray particles.

Aug 10, 2016 · SOURCES OF GAMMA RAYS. Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.

May 14, 2024 · Various natural and artificial sources release gamma radiation: Natural Radioactive Decay: Elements like uranium, thorium, and radium decay and emit gamma rays. Cosmic Sources: High-energy processes in space release gamma rays, such as supernovae, neutron stars, and black holes.

Dec 21, 2024 · 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 …

Dec 28, 2022 · On Earth, gamma rays are produced by radioactive decay, nuclear weapons and lightning, while in space they are produced by violent, high-energy sources such as solar flares, quasars, black...

The top sources within our galaxy include the sun; a star system known as LSI +61 303, which pairs a massive normal star with a superdense neutron star; PSR J1836+5925, which is one of many new pulsars, a type of spinning neutron star that emits gamma-ray beams; and the globular cluster 47 Tucanae, a sphere of ancient stars 15,000 light-years away.

Gamma rays, also known as gamma radiation, refer to electromagnetic radiation (no rest mass, no charge) with very high energies. Gamma rays are high-energy photons with very short wavelengths and thus very high frequency.

Dec 6, 2011 · Gamma-rays are the highest-energy form of light in the universe. Some are generated by transient events, such as solar flares and the huge star explosions known as supernovas. Others are...

Mar 3, 1997 · 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 association with known objects or phenomena in the Milky Way.

Like the discreet atomic energy levels which give rise to specific photon energies, the well defined nuclear states are the source of specific gamma ray energies. We use the two most common of such sources: 137 Cs, which gives off a 662 keV gamma, and 60 …
