Question # 1

What information if revealed by the length and shape of track of an incident particle in Wilson Cloud Chamber?

  • Ans 1: In a wilson cloud chamber
    1. Alpha particle have larger mass and greater ionizing power so its path is straight.
    2. Beta particle have less mass and less ionizing power,so its path is thinner shorter and discontinuous.
    3. Gamma particle have no mass and high penetrating power,so its leaves no definite track along its path,

Question # 1

What is meant by dose of radiation?What is its SI units?

  • Ans 1: Radiation dose is a measure of the amount of exposure to radiation.There are three kinds of dose:
    1. Absorbed dose: it is the amount of energy deposited by radiation in a mass.
    D=E/m its SI unit is Gy.
    2.Equivalent dose: It is calculated for individual organ
    De=D*RBE
    3.Effective dose: It is calculated for the whole body,It is also measured ni Sv.
