Question

Select One Option correct from the following: Consider $\alpha-particles$,$\beta-particles$,$\gamma-particles$ each having an energy of 0.5 MeV. In increasing order of penetrating powers, the radiations are
(A)$\alpha, \beta, \gamma$
(B)$\beta, \gamma, \alpha$
(C)$\gamma, \beta, \alpha$
(D)$\alpha, \gamma, \beta$

Answer 1

hey

It's option C

order of penetration power is

$\gamma > \beta > \alpha$

hope this ans helps you..

Answer 2

gamma>beta>alpha is the correct order

As alpha has lowest penetrative power
