The ionizing capability of gamma rays is:
- A
Equal to alpha and beta particle
- B
Less than alpha but greater than beta particles
- C
Less than both alpha and beta particles
- D
Less than beta but greater than alpha particles
Ionizing capability is the strongest in alpha particles then beta particles and weakest in gamma rays.
Option A is incorrect because gamma rays are electromagnetic waves, not particles, and therefore do not have mass or charge like alpha and beta particles.
Option B is incorrect because alpha particles have higher ionizing capability than gamma rays, despite being less penetrating due to their larger mass and charge.
Ionizing capability is the strongest in alpha particles then beta particles and weakest in gamma rays.
Option D is incorrect because alpha particles have greater ionizing capability than both gamma and beta particles due to their larger mass and charge.
