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.
