Nuclear Physics and RadioactivityEasy
Question
Consider α- particle, β - particle and γ- particle each having an energy of 0.5 MeV. In increasing order of penetrating powers, the radiations are
Options
A.α, β, γ
B.α, γ, β
C.β, γ, α
D.γ, β, α
Solution
Penetrating power is maximum for γ- rays, then of β-particle and then α - particles because basically it depends on the velocity. However, ionization power is in reverse order.
