A radioactive source emits three types of radiations.
Name the three radiations.
In following Figure shows a radioactive source S in a thick lead walled container having a narrow opening. The radiations pass through an electric field between the plates A and B.
- Complete the diagram to show the paths of α, β and γ radiations.
- Why is the source S kept in a thick lead walled container with a narrow opening?
- Name the radiation which is unaffected by the electrostatic field.
- Which radiation is defleced the most. Given reason.
- Which among the three radiations causes the least biological damage?
Explain why alpha and beta particles are deflected in an electric or a magnetic field, but gamma rays are not deflected in such a field.
State the speed of each of α, β and γ radiations.
What is the composition of α, β and γ radiations?
Arrange the α, β, and γ radiation in ascending order of their biological damage. Give reason.
Compare the ionising powers of α, β and γ radiations.
What are α-and β-radiations?
A beam of α, β and γ rays is travelling through a certain region in space.
- Arrange them in ascending order of ionising power.
- Which of the above will pass undeviated if subjected to an electric field?
- With respect to your answer to part (b) above, what will be the change in the nucleus of an atom after such a ray is emitted.
Arrange the α, β and γ radiations in ascending order of their penetrating power.
