- is a measure of quantity of ionisation, produced in air, by x-ray, or gamma radiation per unit mass

- SI unit is the Coulomb per kg (C/kg)

Absorbed dose 

- is a measure of the amount of energy imparted to matter by ionising radiation per unit mass of irradiated material

- SI unit is the Gray(Gy)

Dose equivalent
