Identify each type of radiation as ionizing or non-ionizing. remember that ionizing radiation deposits enough energy when absorbed in a material such that electrons are removed from atoms to create charged ions.
non-ionizing: visible light
ionizing: alpha particles (he nuclei)
non-ionizing: microwaves
ionizing: gamma rays
non-ionizing: infrared
ionizing: beta particles (electrons, positrons)
non-ionizing: radio waves
ionizing: x-rays
