Question # 1

Differentiate between controlled and uncontrolled reaction.

Ans 1: To maintain a sustained controlled nuclear reaction,for every 2 or 3 neutrons released ,only one must be allowed to strike another uranium nucleus.it is called controlled chain reaction.
Ans 2: If more than one neutron produces further fission then it will grow uncontrolled and called uncontrolled chain reaction.

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

What is self-quenching in Geiger Muller Counter?

Ans 1: A small amount of gas is added into the GM counter is called self quenching or internal quenching,In GM counter the phenomena of quenching is to save the counter from spurious or false counts.

Question # 1

Describe a brief account of interaction of various types of radiations with matter.

Ans 1:
1. An a particle has well defined range in a medium ,before coming to rest which is called range if a-particle.
2. It lose its energy due to excitation and ionization of atoms and molecules in matter.
Ans 2: b-particle:
1. The ionizing ability of b particles is about 100 times less than that of a alpha particle.
2. The range of b particle is 100 times more than that of a- particle.
