Free radicals are charged atoms or molecules with an unpaired electron, making them highly reactive and unstable. Their formation is not solely due to X-ray photon ionization of water; it occurs through various processes. For example, a hydroxyl radical can be formed through ionizing radiation impacting water molecules and creating radical-cations that lead to the production of the highly reactive hydroxyl radical.
