How is the ionising and penetrating powers of α, β and γ radiations compared with each other?

Answer»

Comparison of Ionising power of α, β,γ Heavier particle has high ionising power. 

a → 10,000 times of α and 100 times of β 

P → 100 times of α 

∴ Maximum ionising power a, minimum ionising power γ. 

Comparison of Penetrating power of α, β and γ 

Light particle has maximum speed hence maximum penetrating power. 

α has very large penetrating power up to a few hundred meter in air. 

α has small penetrating power (being very heavy) 3 to 8 cm in air

 β- has large penerating power up to few meter in air α < β < γ.
