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

Define absorbed dose and Gray.

  • Ans 1: Absorbed dose:It is defined as the amount of energy absorbed from an ionizing radiation per unit mass of the absorbing body i.e.
    Absorbed dose=energy/mass
    Gray: it is defined as the amount of energy equal to one joule absorbed by a body of mass 1kg i.e
    gray=1 joule/1 kg
