Ionizing radiation, also spelled ionising radiation, consists of subatomic particles or electromagnetic waves that have enough energy per individual photon or particle to ionize atoms or molecules by
Cloud chambers are used to visualize ionizing radiation. This image shows the tracks of particles, which ionize saturated air and leave a trail of water vapour.
Ionized air glows blue around a beam of particulate ionizing radiation from a cyclotron

…electrons from them. Some particles can travel up to 99% of the speed of light; their electromagnetic waves are on the high-energy portion of the electromagnetic spectrum. Gamma rays, X-rays, and the higher energy ultraviolet part of the electromagnetic spectrum are ionizing radiation. Lower energy ultraviolet, visible…
