Question

In the case of radioactivity, arrange $\alpha ,\beta$ and $\gamma$ radiations in ascending order with respect to their:
(i) Penetrating power
(ii) Ionising power
(iii) Biological effect

Answer 1

(i) $\alpha ,\beta$ and $\gamma$ radiations are arranged in the ascending order with respect to their penetrating power as:

$\alpha <\beta <\gamma$

(ii) $\alpha ,\beta$ and $\gamma$ radiations are arranged in the ascending order with respect to their ionising power as:

$\gamma <\beta <\alpha$

(iii) $\alpha ,\beta$ and $\gamma$ radiations are arranged in the ascending order with respect to their bological effect as:

$\alpha <\beta <\gamma$
