प्रश्न
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.

उत्तर
The given figure shows the path of radiation in the magnetic field. The source is kept in a thick-walled lead container so that it.
Radiations may not come out in the undesired direction otherwise they will harm the person working on.
