Ionizing radiation is radiation that has sufficient energy to remove electrons from the orbits of nuclei, thus creating more positively charged atoms or “ionizing” them. Examples: Alpha particles (α), beta particles (β), gamma rays (γ), and galactic cosmic radiation (GCR), which is radiated from space.
Web13 apr. 2024 · As ionizing radiation, including gamma rays and high-energy neutrons, passes unhindered through atomic structures, a transfer of energy strips electrons from atoms causing significant molecular damage. Low energy, non-ionizing electromagnetic radiation does not pose the same magnitude of threat because spacecraft are often …
