Effective dose

the effective dose is calculated as:

$E = \sum\limits_T w_T \cdot [\frac{H_T^M + H_T^F}{2}]$

where $H_T^M$ and $H_F^M$ are the equivalent doses to the tissues or organs $r_T$ of the Reference Adult Male and the Reference Adult Female, respectively and $w_T$ is the tissue weighting factor for target tissue T, with $\sum\limits_T w_T = 1$.

Effective dose is a weighted average of equivalent doses to organs/tissues. The averaging is performed over all organs and tissues of the human body for which radiation detriment can be quantified and for which $w_T$ values are assigned. As $w_R$ and $w_T$ are dimensionless, the SI unit for effective dose is the same as for absorbed dose J kg^(-1) and its special name is sievert (Sv).
