Question # 1

Define background radiations.What are their sources?

Ans 1: When no radioactive source is placed near the radiations detector,it records radiations,These radiations are called background radiations.
Its source are
1. The cosmic rays which come to us from outer space.
2. Radioactive substance present is the Earth's crest.
3. Radioactive potassium and carbon in the body.

Question # 1

Define Half line and discuss its dependence.

Ans 1: The half line T_1/2of a radioactive elements is that period in which half of the atom decay.
Dependence: The number of decaying atoms is proportional to the number of atoms present in the beginning of the period and is proportional to time interval.

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.
