Amongst α,β,γ, rays, α particle has maximum penetrating power.
Open in App
Solution
The correct option is B False
Amongst α,β,γ ways, γ rays, γ− rays have maximum penctrating powerα− 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.
