Question # 1

What is the function of control rods in nuclear reactor?

Ans 1: Controls rods made of Cadmium or Boron are used for the control of number of neutrons,so that of all the neutrons produced in fission ,only one neutrons produces further fission reaction.
In case of emergency or for repair purpose control rods are used to stop the chain reaction and shut down the reactor.

Question # 1

What are isotopes?What do they have common and what are their difference.

Ans 1: Isotopes are such nuclei of an element that have the same charge number Z but have different mass number A.It means,in the nucleus the number of protons is the same but the number of neutrons is different.

Question # 1

Define half-line of radioactive element.How is it related with decay constant?

Ans 1: Half-line:T_1/2is the period in which half of the atom of a radioactive element decay.
It is related with a decay constant by formula.
T_1/2= 0.693/Λ

Question # 1

What information if revealed by the length and shape of track of an incident particle in Wilson Cloud Chamber?

Ans 1: In a wilson cloud chamber
1. Alpha particle have larger mass and greater ionizing power so its path is straight.
2. Beta particle have less mass and less ionizing power,so its path is thinner shorter and discontinuous.
3. Gamma particle have no mass and high penetrating power,so its leaves no definite track along its path,
