Absorbed dose, [math]D[/math], averaged over an organ or tissue region, [math]T[/math], as:
[math] D_T=\frac{\epsilon_T}{m_T} [/math]
Where [math]\epsilon_T[/math] is the mean total energy imparted in a tissue or organ [math]T[/math], and [math]m_T[/math] is the mass of that tissue or organ.

The mean absorbed dose [math]D_T[/math] to a target organ or tissue [math]T[/math] is the sum of the contributions, [math]D(T \leftarrow S)[/math], arising from nuclear transformations of the radionuclide in various source organs [math]S[/math], i.e.:
[math] D_t = \sum_{S} D(T \leftarrow S) [/math]
from ICRP Publication 130, 2015 and ICRP Publication 133, 2016
The mean absorbed dose in a specified organ or tissue region [math]r_T[/math] is given by:
[math] D_T = \frac{1}{m_T} \int D\ dm [/math]
where [math]m_T[/math] is the mass of the organ or tissue and [math]D[/math] is the absorbed dose in the mass element [math]dm[/math]. The SI unit of mean absorbed dose is joule per kilogramme (J kg-1) and its special name is gray (Gy).
