    Radiation - Wikipedia

    https://en.wikipedia.org/wiki/Radiation

    In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)particle radiation, … See more

    Ionizing radiation

    Radiation with sufficiently high energy can ionize atoms; that is to say it can knock electrons off atoms, creating ions. Ionization occurs when an electron is stripped (or "knocked out") from an electron shell of the … See more

    Non-ionizing radiation

    The kinetic energy of particles of non-ionizing radiation is too small to produce charged ions when passing through matter. For non … See more

  3. Electromagnetic radiation - Wikipedia

    https://en.wikipedia.org/wiki/Electromagnetic_radiation

    In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum.

    https://en.wikipedia.org/wiki/Ionizing_radiation
    Image
    Ionizing radiation may be grouped as directly or indirectly ionizing. Any charged particle with mass can ionize atoms directly by fundamental interaction through the Coulomb force if it carries sufficient kinetic energy. Such particles include atomic nuclei, electrons, muons, charged pions, protons, and energetic charged nuclei st…
