Which one of the following radiation possesses maximum penetrating power ?
Correct answer: C. γ-rays
- A. X-rays
- B. B-rays
- C. γ-rays
- D. All have the equal penetrating powe
Explanation
Gamma rays have the greatest penetrating power among alpha, beta and gamma radiation because they are high-energy photons with no charge or rest mass, so they are not easily deflected or stopped. The likely mistake is choosing beta rays because beta particles penetrate farther than alpha particles, but gamma rays penetrate farther than both.

About Radioactive Decay
Radioactive decay is the spontaneous transformation of unstable nuclei, described by decay constant, activity, half life and the exponential decay law. Work includes alpha, beta and gamma emissions, decay equations and remaining nuclei, with half life distinguished from the time required for complete decay.
