A radioactive source emits three types of radiations.
Name the three radiations.
The diagram in figure shows a radioactive source S placed in a thick lead walled container. The radiations given out are allowed to pass through a magnetic field. The magnetic field (shown as ×) acts perpendicular to the plane of paper inwards. Arrows shows the paths of the radiation A, B and C.
- Name the radiations labelled A, B and C.
- Explain clearly how you used the diagram to arrive at the answer in part (a).
State following four properties each of α, β and γ radiations:
- Nature,
- Charge,
- Mass and
- Effect of electric field.
A radioactive substance emits radiations ______.
Compare the penetrating powers of α, β and γ-radiations.
Compare the ionising powers of α, β and γ 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.
Which nuclear radiation will travel undeviated in an electric field?
Which of the following radiations suffer maximum deflection in a magnetic field?
Arrange the α, β and γ radiations in ascending order of their penetrating power.
