Ionizing radiation removes or adds electrons to atoms, creating ions.

Ionizing radiation is defined by its ability to remove or add electrons to atoms, creating ions. This happens when the radiation carries enough energy to overcome the electrons’ binding energy, ejecting an electron and leaving an ion behind (with free electrons that can cause further effects). The description that matches this concept explicitly states that radiation removes or adds electrons to atoms, creating ions. Other statements describe different aspects—speeding electrons, traveling only as waves with no particle interactions, or simply warming tissue—which do not capture the essential ionization process of creating ions.
