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

Distinguished between nuclear fission and nuclear fusion.

  • Ans 1: Nuclear Fission: Such a reaction in which a heavy nuclei like that of uranium splits up into two of roughly equal size along with the emission of energy is called fission reaction.
  • Ans 2: Nuclear Fusion:A reaction in which two lights nuclei merge to form a heavy nucleus is called fusion reaction.It require very high temperature.
