Which is incorrect statement in the following?

Options

  1. Aα -rays have more penetrating power than β -rays
  2. Bα -rays have less penetrating power than γ -rays
  3. Cβ -rays have less penetrating power than γ -rays
  4. Dβ -rays have more penetrating power than α -rays

Correct answer

A. α -rays have more penetrating power than β -rays

Step-by-step solution

The order of penetrating power is : α < β < γ -rays. It is due to lower mass and high speed.
