WebIonization. As an example of ionization, beta rays are fast electrons that lose energy as they pass through cells and interact with molecules. The transferred energy is high enough to disrupt chemical bonds, which results in radical formation (or ionization). Ionization differs from the ion formation that occurs in ordinary chemical reactions. Web7 mrt. 2024 · 11.
