Which of the radioactive radiations :
(i) Can cause severe genetical disorders.
(ii) Are deflected by an electric field?

Q. A radioactive source emits three types of radiations. The radiations which are deflected by the electric field are:

Q. Match the following

Radiation from radioactive material	Particle
(i) having positive charge	(a)$\alpha$
(ii) is most penetrating	(b)$\beta$
(iii) easily deflected by magnetic field	(c) $\gamma$
(iv) is not deflected by an electric field
(v) causes most intense ionisation

Q. $\left(i\right)$ Complete the diagram as given alongside by drawing the deflection of radioactive radiations in an electric field.
$\left(ii\right)$ State any two precautions to be taken while handling radioactive substances.

Q. Fig. shows a radioactive source S in a thick lead walled container having a narrow opening. The radiation passes through an electric field between the plates A and B.​

Q. Complete the diagram as given below by drawing the deflection of radioactive radiations in an electric field. What are some precautions that must be taken care of while handling radioactive substance? [5 MARKS]
