Interpretation: Though gamma rays are much more penetrating than alpha rays still the latter is more harmful, the reasons for it has to be explained. Also which ray is more ionizing has to be stated.
Concept introduction: Nuclear reactions are those where an unstable nuclide disintegrates in order to form a stable nuclide with emission of various radiations feasibly. It is called radioactivity of nucleus. The particles or rays emitted during the process are alpha, beta and gamma rays which cause a change in the identity of nucleus.
Beta particle is one that has unit negative charge and alpha particle is one that has 2 unit positive charges and is equivalent to helium atom

Answer to Problem 49A
Though
Explanation of Solution
When radioactive substance disintegrates, three types of radiations are produced:
Though
