Tips: What is Absorbed Dose?

Absorbed dose is the energy given per unit mass of material by ionizing radiation. The strict definition is the quotient of the average conferred energy dE of ionizing radiation to a substance of mass DM divided by DM, denoted by D. Its si unit is Gy, 1Gy=1 J/Kg. The customary unit used was Rad. 1 rad =0.01 Gy.

The physical, chemical, or biological changes caused by radiation applied to a substance depend first on the amount of radiation energy absorbed per unit mass of the substance. So absorbed dose is an important physical quantity. But studies have shown that different types of radiation, even if the same dose of the same substance is absorbed, can cause different changes, especially in the degree of biological damage. For example, the damage caused by a dose of 0.01 Gy fast neutrons is comparable to the damage caused by a dose of 0.1 Gy γ-radiation, that is, the damage factor of fast neutrons is 10 times that of γ-radiation.
