Solution

The correct option is B False
Amongst α,β,γ ways, γ rays, γ rays have maximum penctrating power
α particles have small penetrating power due to relatively larger size. They are stopped by a piece of aluminium foil of 0.1 mm thickness.
β rays are more penetrating than α particles. This is due to small size and high velocity. These are stopped by a 1 am thick sheet of aluminium.
Due to high velocity and non-material character, γ ways are 1010 times more penetrating than α rays.
