Absorbed dose (also known as Total Ionizing Dose, TID) is a measure of the energy deposited in a medium by
ionizing radiation. It is equal to the energy deposited per unit mass of medium, and so has the unit J/kg, which is given the special name
gray (Gy).Note that the absorbed dose is not a good indicator of the likely biological effect. 1 Gy of
alpha radiation would be much more biologically damaging than 1 Gy of
photon radiation for example. Appropriate weighting factors can be applied reflecting the different relative biological effects to find the
equivalent dose.
