What is Ionizing Radiation?

Electromagnetic radiation can either be be non-ionizing or ionizing.^2,5,6,7 Non-ionizing electromagnetic radiation consist of energies that are typically <5eV. These produce low energy radiation such as visible light, microwaves, and radio waves. Ionizing electromagnetic radiation on the other hand, has energies of >5eV volts that are able to remove electrons from an atom and produce high-energy radiation, such as gamma rays and x-rays.
