Which type of radiation includes gamma rays?

Gamma rays are a form of electromagnetic radiation that possess high energy and short wavelengths, which makes them capable of ionizing atoms and molecules. This means that gamma rays have enough energy to remove tightly bound electrons from atoms, creating ions. Because ionization can cause damage to biological tissues and DNA, gamma rays are classified as ionizing radiation.

In contrast, non-ionizing radiation, which includes types like radio waves and microwaves, has lower energy and is not capable of ionizing atoms. High-frequency radiation generally refers to radiation with higher frequencies than visible light, including ultraviolet radiation, but it doesn't specifically categorize gamma rays. Light radiation primarily pertains to visible light wavelengths, which again do not include the energetic gamma rays. Thus, the classification of gamma rays as ionizing radiation is critical in understanding their potential effects on living organisms and the environment.
