Final answer:
Gamma radiation is known as ionizing radiation due to its ability to create charged particles by removing electrons from atoms.
Step-by-step explanation:
The form of radiation that is capable of creating electrically charged particles by removing orbital electrons from the atom of normal matter through which it passes is called ionizing radiation. Among the types of radiation—alpha rays, beta rays, and gamma ray
s—it is the gamma radiation that is specifically known for this property. Gamma rays are a very energetic form of electromagnetic radiation that can knock electrons out of atoms, resulting in the formation of ions. In contrast, alpha radiation, composed of helium nuclei, and beta radiation, comprised of high-energy electrons or positrons, also have ionizing capabilities but are distinguished by their mass and charge.
