Question # 1

Wh Geiger counter is not suitable for fast counting?

Ans 1: Geiger counter is not suitable for fast counting because of its longer dead time.The positive ions take several time as long to reach the outer cathode,because positive ions are very massive than the electrons.During this time further incoming particle can not be counted,This time is called as the dead time of counter which delays fast counting system.

Question # 1

What is meant by dose of radiation?What is its SI units?

Ans 1: Radiation dose is a measure of the amount of exposure to radiation.There are three kinds of dose:
1. Absorbed dose: it is the amount of energy deposited by radiation in a mass.
D=E/m its SI unit is Gy.
2.Equivalent dose: It is calculated for individual organ
D_e=D*RBE
3.Effective dose: It is calculated for the whole body,It is also measured ni Sv.
