Which statement best describes gamma radiation's penetrating capability?

• A. It mostly affects skin
• B. It has high penetrating ability and reaches inner organs
• C. It does not penetrate
• D. It only affects magnetic fields

Answer: (B)

Gamma radiation has high penetration power, so it can pass through skin and many materials and reach internal organs. That deep-penetrating nature means exposure isn’t limited to surface tissues; shielding needs to be dense and thick, and distance helps reduce dose. So the statement that gamma rays have high penetrating ability and can reach inner organs best describes how they behave. The other ideas—being stopped at the skin, not penetrating at all, or only affecting magnetic fields—don’t fit gamma radiation, since it is electromagnetic energy that travels through the body and is not primarily influenced by magnetic fields.
