It is used in industries to destroy the harmful bacteria, organism such as yeast etc.
It is used for treatment of cancer cell in our body with no use of the surgery.
Like x – rays, it is also used to sterilize medical instruments.
It is used to detect heart and brain abnormalities.
Gamma rays are used by Engineers, because they can penetrate better than X-rays, to search for cracks in pipes and aircraft parts..
One of many destructive use is their essential role in progression of the atomic bomb.
The gamma rays are much like other electromagnetic rays that are emitted by various sources under various circumstances. These are released by the hottest part of our universe and also these are released by the radioactive decay of certain material, such as zinc-65, cobalt-60, radium-226 and cesium-137.
The Gamma Rays are produced in number of ways:
Matter-Antimatter Annihilation: This procedure is observed when an electron and positron goes through a procedure of annihilation where the neutral particles are created and these particles decay into gamma rays.
Particle-Particle Collision: This effect is noticed when cosmic rays or proton collides one another they produces neutral particle that are moving with higher velocity. These particles decay to the gamma rays.
Acceleration of charged particles: Whenever a charged particle is accelerated under the force of magnetic force while moving within the magnetic field it radiate a electromagnetic radiation within the gamma region.
Radioactive Decay: Whenever a high energy nucleus adjustments its state to lower energy, it produces a gamma rays. This effect is called radioactive decay. Throughout the radioactive decay the nuclei might emit alpha, gamma rays, beta.
Gamma rays are radiation via nuclear decay, whenever a nucleus modifications from an excited energy state to some lower energy state. Gamma rays are generally waves of frequencies higher than 1019 Hz. They have higher energies (more than 104 eV per photon) and very short wavelengths (lower than 10-14 m).
Gamma rays can penetrate almost all materials and are therefore hard to detect. Gamma rays mostly have been detected in the activities in space including the Vela Pulsar and the Crab Nebula. The greatest frequency of gamma rays that have been detected is 1030 Hz calculated from diffuse gamma ray emissions.
