Absorbed dose
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.

absorbed dose
The amount of energy imparted by nuclear (or ionizing) radiation to unit mass of absorbing material. The unit is the rad. 1/2/73
dose absorbée
Quantité d'énergie cédée par des particules ionisantes à l'unité de masse de la substance irradiée, au point considéré, quelle que soit la nature du rayonnement utilisé. L'unité de dose absorbée est le rad. 1/2/73
Absorbed Dose
In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g. skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with
internal dose.
Dose, absorbed
The amount of energy deposited in any substance by ionizing radiation per unit mass of the substance. It is expressed numerically in rads or grays.
