Sterilization can be achieved using electromagnetic radiation, such as ultraviolet light (UV), X-rays, and gamma rays, or irradiation by subatomic particles such as electron beams. [57] Electromagnetic or particulate radiation can be energetic enough to ionize atoms or molecules ( ionizing radiation ), or less energetic atoms or molecules ( non ...
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 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.
Irradiation is the process by which an object is exposed to radiation. An irradiator is a device used to expose an object to radiation, notably gamma radiation , for a variety of purposes. [ 1 ]
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. This is due to the higher dose rates and shorter exposure times of e-beam irradiation, which have been shown to reduce the degradative effects of oxygen. [18]
The first gamma ray source to be discovered was the radioactive decay process called gamma ... irradiation. Applications of this include the sterilization of ...
It is used as a unit of the radiation quantity absorbed dose that measures the energy deposited by ionizing radiation in a unit mass of absorbing material, and is used for measuring the delivered dose in radiotherapy, food irradiation and radiation sterilization.
The Nordion Gamma Centre of Excellence (GCE) is a gamma irradiation research, training, and demonstration facility located in Laval, Quebec, Canada. The GCE is operated in partnership with the University of Quebec's Armand Frappier Institute. Nordion has an Asia Pacific Sales Office in Hong Kong.
