Question

Arrange in increasing order of penetrating powers, considering each radiation particle has the same energy of 0.5MeV. (A) &alpha;, &beta;, &gamma; (B) α, γ, β (C) β, γ, α (D) γ, β, α

Penetrating power is maximum for &gamma; - rays, then of &beta; -particles and then &alpha; - particles because basically it depends on the velocity. However, ionization power is in reverse order.
