   Nov 3, 2024 · Gamma rays are produced during the disintegration of radioactive atomic nuclei and the decay of certain subatomic particles. Gamma rays are also produced through the process of pair annihilation, in which an electron and its antiparticle, a positron, vanish and two photons are created.

   Mar 18, 2024 · In just a few seconds, a gamma-ray burst releases more energy than our sun is capable of generating in the entirety of its lifetime, or 10 billion years. To produce such a catastrophic energy projectile, an equally powerful explosion is in order, which is where gamma-ray bursts come from.

   How gamma rays are produced on Earth?

   • On Earth, gamma waves are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay. Unlike optical light and x-rays, gamma rays cannot be captured and reflected by mirrors. Gamma-ray wavelengths are so short that they can pass through the space within the atoms of a detector.

   What are gamma rays?

   • Gamma rays are high-energy photons produced by some of the most violent events in the universe. Photons of light are massless particles that are essentially packets of energy. Because of a quantum-mechanical phenomenon known as wave-particle duality, particles can behave like waves, and photons are no different.

   How do gamma rays decay?

   • It can then decay to a lower energy state by emitting a gamma ray photon, in a process called gamma decay. The emission of a gamma ray from an excited nucleus typically requires only 10 −12 seconds. Gamma decay may also follow nuclear reactions such as neutron capture, nuclear fission, or nuclear fusion.

   Where do gamma ray bursts come from?

   • To produce such a catastrophic energy projectile, an equally powerful explosion is in order, which is where gamma-ray bursts come from. As stars age, they slowly burn through the fuel that keeps them from collapsing in on themselves due to their gravity.

   What is the wavelength of gamma ray?

   • Gamma-ray radiation has wavelengths generally smaller than a few tenths of an angstrom (10 meter), and gamma-ray photons have energies greater than tens of thousands of electron volts. How are gamma rays produced? Gamma rays are produced during the disintegration of radioactive atomic nuclei and the decay of certain subatomic particles.
