A gamma ray, also known as gamma radiation (symbol γ or ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei.It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium Irradiation by gamma rays has a number of applications in agriculture and food industry. While naturally-occurring rays do not have the energy needed to make atoms radioactive, they do have an impact on the sub-molecular world The main applications of Gamma rays in the field of medicine are- Radiation therapy- These therapies are used to treat infectious and cancerous tumors. In this process, high energy gamma rays are directed by implanting or injecting a radioactive isotope near the tumor to kill it
Among the radionuclides suitable for metabolic studies, iodine-131 is one of the most widely used. This gamma-ray emitter has a half-life of eight days and concentrates in the thyroid gland, and so provides a measure of thyroid function Electromagnetic radiation is generally referred to as gamma-radiation when emitted by the nucleus, and X-radiation when originating from the electrons orbiting the nucleus. Elements that emit one or more of these radiations are termed radioactive, a derivation of the Latin word radius, meaning ray
Gamma rays, also known as gamma radiation, refers to electromagnetic radiation (no rest mass, no charge) of a very high energies.Gamma rays are high-energy photons with very short wavelengths and thus very high frequency. Since the gamma rays are in substance only a very high-energy photons, they are very penetrating matter and are thus biologically hazardous Gamma rays are the highest energy photons (shortest wavelength, highest frequency), arising out of nuclear events during radioactive decay. For in vivo applications, the best gamma rays are of low energy (100-511 keV) because they can penetrate tissues. Gamma rays in this energy range can also be efficiently stopped, and therefore measured by. Gamma-ray (γ-ray) spectroscopy is a quick and nondestructive analytical technique that can be used to identify various radioactive isotopes in a sample. In gamma-ray spectroscopy, the energy of incident gamma-rays is measured by a detector Depth correlations and core-log integration. Total gamma-ray log curves, which are acquired with every toolstring combination, are normally used to depth match all of the logs obtained in any one hole. The HSGR log from the Triple Combo is used as the base curve, and the SGR logs from all the other toolstrings are interactively matched to it. The depth shift applied to each SGR curve is.

Gamma Ray Attenuation. Gamma ray attenuation is a concept, that can be used for approximate calculation of radiation shielding. It is based on the theory that gamma rays can never be completely stopped, but only attenuated. The attenuation of a gamma rays is defined as the fraction of rays which come through an absorber without interacting Gamma-rays. Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions.

Gamma radiation isn't emitted by itself, only after another event like alpha or beta decay. Normally it's emitted at almost exactly the same time. Gamma rays can pass through lead but aren't very damaging. Gamma rays can pass through a thin sheet of lead with very little effect. You need about 10 cm of lead to stop most gamma rays completely Because X-rays and gamma rays have the same properties and health effects, they are grouped together in this document. Both x-rays and gamma rays are forms of high-frequency ionizing radiation, which means they have enough energy to remove an electron from (ionize) an atom or molecule. Ionized molecules are unstable and quickly undergo chemical. Application of such spectral gamma ray data may be made either qualitatively or quantitatively. As is extensively documented in logging literature, natural spectral gamma ray logging assists greatly in geological studies (lithology identification, recognition of depositional environment, stratigraphic correlation, source rock evaluation, etc.

Even with such intense barriers, some radiation may still get through because of how small the rays are. Though the least ionising of all the forms of radiation, that doesn't mean Gamma rays aren't dangerous The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer. Ironically, the deadly effects of gamma rays can be used to treat cancer
The choice of a particular detector type for an application depends upon the X-ray or gamma energy range of interest and the application's resolution and efficiency requirements.
