A radioactive source emits three types of radiations.
Name the three radiations.
In following Figure shows a mixed source R of alpha and beta particles in a thick lead walled container. The particles pass through a magnetic field in a direction perpendicular to the plane of paper inwards as shown by ×.
- Show in the diagram how the particles get affected.
- Name the law used in part (a).
[Hint: Alpha particles will deflect to the left while beta particles to the right]
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.
Is it possible to deflect γ - radiations in a way similar to α and β -particles, using the electric or magnetic field? Give reasons.
State following four properties each of α, β and γ radiations:
- Nature,
- Charge,
- Mass and
- Effect of electric field.
Arrange the α, β, and γ raditions in ascending order of their ionising powers.
Compare the penetrating powers of α, β and γ-radiations.
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.
