Gamma irradiation is exposure to ionizing radiation with gamma rays. It may also refer to the following processes in particular: Ionizing radiation sterilization; Food irradiation; Gamma knife, used in radiosurgery
Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection , sanitization, and pasteurization , in that those methods reduce rather than eliminate all forms of life and biological agents present.
Electron-beam processing or electron irradiation (EBI) is a process that involves using electrons, usually of high energy, to treat an object for a variety of purposes. This may take place under elevated temperatures and nitrogen atmosphere.
Ionizing radiation such as gamma rays, electron beam, X-rays can be used to provide phytosanitary treatment. The direct effect of these high energy photons and electrons, as well as the free radicals they produce result in sufficient damage to large organic molecules such as DNA and RNA resulting in sterilization, morbidity or mortality of the target pests.

Irradiation is the process by which an object is exposed to radiation. An irradiator is a device used to expose an object to radiation, [ 1 ] most often gamma radiation , [ 2 ] for a variety of purposes.
The international Radura logo, used to show a food has been treated with ionizing radiation. A portable, trailer-mounted food irradiation machine, c. 1968 Food irradiation (sometimes American English: radurization; British English: radurisation) is the process of exposing food and food packaging to ionizing radiation, such as from gamma rays, x-rays, or electron beams.
The international type IV (wet storage) irradiator is a common design, of which the JS6300 and JS6500 gamma sterilizers (made by 'Nordion International', which used to trade as 'Atomic Energy of Canada Ltd') are typical examples. [25] In these irradiation plants, the source is stored in a deep well filled with water when not in use.
By causing the materials to become radioactive (mainly by neutron activation, or in presence of high-energy gamma radiation by photodisintegration). By nuclear transmutation of the elements within the material including, for example, the production of Hydrogen and Helium which can in turn alter the mechanical properties of the materials and ...
