Which statement best describes how gamma radiation travels?

• A. It Travels in Waves and Affects the Whole Body
• B. It Travels in Waves and Affects Only the Skin
• C. It Travels as Particles
• D. It Does Not Penetrate the Body

Answer: (A)

Gamma radiation is a form of electromagnetic radiation, made up of high-energy photons, so it travels as waves of energy at the speed of light. Because these photons carry a lot of energy and have no electric charge, they can pass through the body and reach internal tissues. That means exposure to gamma rays can affect not just the skin but internal organs as well, depending on the dose and how long exposure lasts. This penetrating power is what makes gamma radiation capable of impacting the whole body rather than being limited to surface tissues. The other descriptions either treat gamma as particles or claim it doesn’t penetrate, which doesn’t fit its well-known ability to pass through and interact with deeper tissues.
