Ionizing radiation is ...

• A. Radiation that produces ionization, resulting in harmful effects.
• B. Radiation that cannot cause any chemical changes.
• C. Radiation that only heats matter.
• D. Radiation that travels at the speed of light.

Answer: (A)

Ionizing radiation is radiation that has enough energy to remove electrons from atoms, creating ions. This ionization can break chemical bonds and damage biological molecules, which is why it can be harmful. Some radiation does not ionize and mainly transfers energy as heat, and the defining feature isn’t speed but the ability to ionize atoms. Examples of ionizing types include X-rays and gamma rays, while non-ionizing forms include visible light, microwaves, and radio waves.
