Question # 1

Describe the principle of operation of solid state detector?

Ans 1: A solid state detector is a specially designed p-n junction operating under a reversed bias in which electron-hole pairs are produced by the incident radiation to cause a current pulse to flow through the external circuit.

Question # 1

Define absorbed dose and Gray.

Ans 1: Absorbed dose:It is defined as the amount of energy absorbed from an ionizing radiation per unit mass of the absorbing body i.e.
Absorbed dose=energy/mass
Gray: it is defined as the amount of energy equal to one joule absorbed by a body of mass 1kg i.e
gray=1 joule/1 kg

Question # 1

What are isotopes?What do you have in common?

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.
