Physics - ICS Part 2 Physics Chapter 21 Short Questions Preparation

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

Which radiation does would deposit more energy to the body(a)10 m Gy to the hand (b)1m Gy dose to entire body.

Ans 1: Since
absorbed dose=D=energy/mass
energy=D * Mass
since the mass of whole body is much greater than mass of the hand,therefore 1 Gy dose given to the entire body deposit more energy.

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.
