Penetration power of gamma rays as compared to alpha rays is
Correct answer: A. Greater
- A. Greater
- B. Less
- C. Equal
- D. Either a or c
Explanation
Gamma rays are electromagnetic radiation, which means they are high-energy photons. They have no mass and no charge, making them highly penetrating. They can easily pass through materials that stop alpha and beta particles, such as thick layers of lead or concrete.Alpha particles, on the other hand, are relatively large and heavy, and they have a positive charge. This makes them highly ionizing, but they have a short range and are easily stopped by a thin sheet of paper or even a layer of air.Therefore, gamma rays have a much greater penetration power than alpha rays

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.
