Gamma radiation is a form of which energy type?

• A. Ionizing energy
• B. Mechanical energy
• C. Thermal energy
• D. Electromagnetic energy

Answer: (D)

Gamma radiation is a form of electromagnetic energy. It travels as high-energy photons with no mass, moving at the speed of light, and sits in the gamma region of the electromagnetic spectrum. While its photons can ionize atoms—so in safety contexts it is described as ionizing radiation—the fundamental energy type is electromagnetic energy, not mechanical or thermal. Mechanical energy relates to motion or position of objects, and thermal energy to temperature-driven molecular motion, so those aren’t appropriate categories for gamma rays.
