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

If you swallowed a alpha source and beta source ,which would be more dangerous to you ?Explain

Ans 1: As alpha particle have greater energy and ionizing power than beta particle,so alpha particle are more dangerous than beta particle.
Critical volume:The volume of critical mass is called critical volume.
