Electron-beam processing involves irradiation (treatment) of products using a high-energy electron-beam accelerator. Electron-beam accelerators utilize an on-off technology, with a common design being similar to that of a cathode ray television. Electron-beam processing is used in industry primarily for three product modifications:
Electron beam technology is used in cable-isolation treatment, in electron lithography of sub-micrometer and nano-dimensional images, in microelectronics for electron-beam curing of color printing [1] and for the fabrication and modification of polymers, including liquid-crystal films, among many other applications.
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 ...
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 ]
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.

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.
These radio emissions are correlated to the video image being displayed, so, in theory, they can be used to recover the displayed image. In a CRT, the image is generated by an electron beam that sweeps back and forth across the screen. The electron beam excites the phosphor coating on the glass and causes it to
