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

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

If nucleus has a life of one year,does this mean that it will be completely decayed after two years?

Ans 1: No it will not decay completely after two years.
Numbers of atom at initial stage =N_o
number of atoms decayed after first year =1/2N_o
