Question # 1

Discuss the advantages of fission power from point of view of safety,pollution and resources.

  • Ans 1: Advantage of nuclear power are given below
    1. Nuclear fission energy,release a highly reduced amount of the gases into the air,resulting in a slower rate of global warming and pollution.
    2. The energy is quick to create;meaning that they are able to make a large amount of some form of emergency required it.
    3. Much more energy is produced.

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.
