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

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

Wh Geiger counter is not suitable for fast counting?

Ans 1: Geiger counter is not suitable for fast counting because of its longer dead time.The positive ions take several time as long to reach the outer cathode,because positive ions are very massive than the electrons.During this time further incoming particle can not be counted,This time is called as the dead time of counter which delays fast counting system.
