उत्तर
Penetration power of α-particle is least and that of γ-radiation maximum α (3 - 8 cm in air), β [upto few meter in air.] and γ [upto few hundred meter in air].

The figure shows a radioactive source S placed in a thick-walled lead container. The radiations given off pass through a magnetic field acting in direction perpendicular to the plane of paper inwards as shown by X. Copy the diagram and show the path of radiations. Explain why the source is kept in a thick-walled lead container.
