Sterilization can be achieved using electromagnetic radiation, such as ultraviolet light, X-rays and gamma rays, or irradiation by subatomic particles such as by electron beams. [57] Electromagnetic or particulate radiation can be energetic enough to ionize atoms or molecules ( ionizing radiation ), or less energetic ( non-ionizing radiation ).
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.
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. Possible uses for electron irradiation include sterilization, alteration of gemstone colors, and cross ...
Irradiation. 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] Irradiators may be used for sterilizing medical and pharmaceutical supplies, preserving foodstuffs, alteration of gemstone colors, studying ...
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.
Sterility assurance level. In microbiology, sterility assurance level (SAL) is the probability that a single unit that has been subjected to sterilization nevertheless remains nonsterile. It is never possible to prove that all organisms have been destroyed, as the likelihood of survival of an individual microorganism is never zero.
