Alpha particles possess greater penetration power than that of beta particles due to its:

Correct answer: A. Smaller ionization power

  • A. Smaller ionization power
  • B. Greater ionization power
  • C. Neither greater nor smaller ionization power
  • D. Same ionization power

Explanation

Alpha particles have greater mass and charge than beta particles, but they have smaller penetration power due to their larger ionization power. Alpha particles interact more strongly with matter and lose their energy quickly, resulting in a shorter penetration range compared to beta particles.

About Nuclear Physics

Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
