The ionization power of _ ray is highest.
Correct answer: D. None of these
- A. Beta
- B. Gamma
- C. He-Ne laser
- D. None of these
Explanation
Among the three types of common radiation, alpha particles have the highest ionization power.Alpha particles are composed of two protons and two neutrons, and they have a positive charge. When they pass through matter, they interact strongly with the electrons and atoms of the material, causing a large number of ionizations. This means that they can knock off electrons from atoms, creating positively charged ions and free electrons, which can go on to create further ionizations.In comparison, beta and gamma radiation have lower ionization 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.
