Gamma rays have high penetrating power than alpha and beta rays due to:
Correct answer: A. No charge
- A. No charge
- B. Non-material nature
- C. Small size
- D. Lighter particles
Explanation
Gamma rays have higher penetrating power than alpha and beta particles due to their lack of charge. Alpha and beta particles carry an electrical charge, these charged particles interact more strongly with matter, resulting in shorter penetrating distances. On the other hand, gamma rays are high-energy photons with no charge. They have electromagnetic radiation and do not carry any electrical charge. As a result, they are not repelled or attracted by charged particles and can pass through matter more easily, giving them high penetrating power.

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.
