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]
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?
Is it possible to deflect γ - radiations in a way similar to α and β -particles, using the electric or magnetic field? Give reasons.
Arrange the α, β, and γ raditions in ascending order of their ionising powers.
Arrange the α, β, and γ radiation in ascending order of their biological damage. Give reason.
A radioactive substance emits radiations ______.
Compare the ionising powers of α, β and γ radiations.
Which nuclear radiation will travel undeviated in an electric field?
Which of the following radiations suffer maximum deflection in a magnetic field?
