  2. Electron therapy - Wikipedia

    en.wikipedia.org/wiki/Electron_therapy

    Electron beam therapy is used in the treatment of superficial tumors like cancer of skin regions, or total skin (e.g. mycosis fungoides), diseases of the limbs (e.g. melanoma and lymphoma), nodal irradiation, and it may also be used to boost the radiation dose to the surgical bed after mastectomy or lumpectomy.

  3. Electron-beam processing - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_processing

    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:

  4. Radiation damage - Wikipedia

    en.wikipedia.org/wiki/Radiation_damage

    Research in this area has focused on the three most common sources of radiation used for these applications, including gamma, electron beam, and x-ray radiation. [17] The mechanisms of radiation damage are different for polymers and metals, since dislocations and grain boundaries do not have real significance in a polymer.

  5. Electromagnetic radiation and health - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation...

    Damage is cumulative over one's lifetime, so that permanent effects may not be evident for some time after exposure. [19] Ultraviolet radiation of wavelengths shorter than 300 nm (actinic rays) can damage the corneal epithelium. This is most commonly the result of exposure to the sun at high altitude, and in areas where shorter wavelengths are ...

  6. Radiation burn - Wikipedia

    en.wikipedia.org/wiki/Radiation_burn

    In water, broad electron beams, as is the case in homogeneous surface contamination of skin, have d 80 about E/3 cm and R p about E/2 cm, where E is the beta particle energy in MeV. [ 24 ] The penetration depth of lower-energy beta in water (and soft tissues) is about 2 mm/MeV.

  7. External beam radiotherapy - Wikipedia

    en.wikipedia.org/wiki/External_beam_radiotherapy

    External beam radiation therapy (EBRT) is a form of radiotherapy that utilizes a high-energy collimated beam of ionizing radiation, from a source outside the body, to target and kill cancer cells. The radiotherapy beam is composed of particles, which are focussed in a particular direction of travel using collimators [ 1 ] .

  8. Electron-beam technology - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_technology

    Electron-beam machining is a process in which high-velocity electrons are concentrated into a narrow beam with a very high planar power density. The beam cross-section is then focused and directed toward the work piece, creating heat and vaporizing the material. Electron-beam machining can be used to accurately cut or bore a wide variety of metals.

  9. Non-ionizing radiation - Wikipedia

    en.wikipedia.org/wiki/Non-ionizing_radiation

    Exposure to non-ionizing ultraviolet light is a risk factor for developing skin cancer (especially non-melanoma skin cancers), sunburn, premature aging of skin, and other effects. Despite the possible hazards it is beneficial to humans in the right dosage, since Vitamin D is produced due to the biochemical effects of ultraviolet light.
