Question # 1

What are thermal reactors?

  • Ans 1: The thermal reactors are called thermal reactors because the neutrons must be slowed down to thermal energies to produce further fission,They use natural uranium or slightly enriched uranium as fuel.

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.
