The symbol also shows the food being irradiated from above, through the packaging, by ionizing rays, which is represented by the breaks in the upper part of the circle. [2] Initially introduced in the 1960s, the Radura symbol was exclusively used by a food irradiation pilot plant in Wageningen, Netherlands, which held the copyright. Jan ...
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.

Sterilization by irradiation with gamma rays may however affect material properties. [62] [63] Irradiation is used by the United States Postal Service to sterilize mail in the Washington, D.C. area. Some foods (e.g., spices and ground meats) are sterilized by irradiation. [64]
Radappertization is a form of food irradiation which applies a dose of ionizing radiation sufficient to reduce the number and activity of viable microorganisms to such an extent that very few, if any, are detectable in the treated food by any recognized method (viruses being excepted).
Electron-beam processing has the ability to break the chains of DNA in living organisms, such as bacteria, resulting in microbial death and rendering the space they inhabit sterile. E-beam processing has been used for the sterilization of medical products and aseptic packaging materials for foods, as well as disinfestation, the elimination of ...
Ion irradiation means in general using particle accelerators to shoot energetic ions on a material. Ion implantation is a variety of ion irradiation, as is swift heavy ions irradiation from particle accelerators induces ion tracks that can be used for nanotechnology. [9] [10]
Dental equipment in an autoclave to be sterilized for 2 hours at 150 to 180 degrees Celsius A medical autoclave is a device that uses steam to sterilize equipment and other objects. This means that all bacteria , viruses , fungi , and spores are inactivated. [ 13 ]
