It is also used to process items that are sensitive to processing with other methods, such as radiation (gamma, electron beam, X-ray), heat (moist or dry), or other chemicals. Ethylene oxide treatment is the most common chemical sterilization method, used for approximately 70% of total sterilizations, and for over 50% of all disposable medical ...
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.
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
The process, which consists of striking plant seeds or germplasm with radiation in the form of X-rays, UV waves, heavy-ion beams, or gamma rays, essentially induce lesions of the DNA, leading to mutations in the genome. The UN has been an active participant through the International Atomic Energy Agency.
Radiation: •Gamma ray source: used in sterilization of heat-labile products like plastic or rubber syringes, catheters and gloves •X-ray source-do- •Infrared light source-do- •Ultraviolet light source-do- Inspissator: used to produce culture media for bacteriology that contain egg or serum, which coagulate on heating Tyndallizer
The process is quick, reliable, and compatible with most materials, and does not require any quarantine following the processing. [17] For some materials and products that are sensitive to oxidative effects, radiation tolerance levels for electron-beam irradiation may be slightly higher than for gamma exposure.
Cobalt therapy, using beams of gamma rays from 60 Co teletherapy machines to treat cancer. Radiation source for industrial radiography. [9] Radiation source for leveling devices and thickness gauges. [9] Radiation source for pest insect sterilization. [10] As a radiation source for food irradiation and blood irradiation. [8]
To process materials, either a gamma source or an electron beam can be used. The international type IV ( wet storage ) irradiator is a common design, of which the JS6300 and JS6500 gamma sterilizers (made by 'Nordion International' [2] , which used to trade as 'Atomic Energy of Canada Ltd') are typical examples.
