Which one of the following radiations possesses maximum penetrating power?
Correct answer: B. γ. rays
- A. α. rays
- B. γ. rays
- C. β. rays
- D. All have equal penetrating power
Explanation
Gamma (γ) rays are high. energy photons with no charge or mass, allowing them to penetrate matter much more deeply than charged particles like alpha (α) or beta (β) rays. Alpha particles are the least penetrating.
