ionization. (chemistry). A process by which a neutral atom or molecule loses or gains electrons, thereby acquiring a net charge and becoming an ion; occurs as the result of the dissociation of the atoms of a molecule in solution (NaCl â Na + + Cl -) or of a gas in an electric field (H 2 â 2H +).
Ionizing Radiation: Any electromagnetic or particulate radiation capable of producing ion pairs by interaction with matter. Scope limited to X and gamma rays, alpha particles, beta particles (electrons), neutrons, and charged nuclei. Particularly important biologically since media can be altered (e.g., ionized atom in DNA molecule may be altered, thereby causing cell death, or a change in cell reproduction, division, or mutation).
