The equivalent dose in an organ or tissue is given by:

[math] H_T = \sum_{R} w_RD_{R,T} [/math]

where [math]D_{R,T}[/math] is the mean absorbed dose from radiation [math]R[/math] in a tissue or organ [math]T[/math], and [math]w_R[/math] is the radiation weighting factor. The SI unit of equivalent dose is joule per kilogram (J kg-1), and its special name is sievert (Sv).

from ICRP Publication 130, 2015

The equivalent dose to a tissue or organ is defined as:

[math] H_T = \sum_{R} w_RD_{R,T} [/math]

where [math]w_R[/math] is the radiation weighting factor for radiation type [math]R[/math], and [math]D_{R,T}[/math] is the organ absorbed dose from radiation type [math]R[/math] in a tissue or organ [math]r_T[/math] of the Reference Adult Male or the Reference Adult Female. As [math]w_R[/math] is dimensionless, the SI unit for the equivalent dose is the same as for absorbed dose, J kg-1, and its special name is sievert (Sv).

from ICRP Publication 133, 2016

The equivalent dose to a tissue or organ is defined as:

[math] H_T = \sum_{R} w_RD_{R,T} [/math]

where [math]w_R[/math] is the radiation weighting factor for radiation type [math]R[/math], and [math]D_{R,T}[/math] is the organ absorbed dose from radiation type [math]R[/math] in a tissue or organ [math]r_T[/math] of the Reference Adult Male or the Reference Adult Female. As [math]w_R[/math] is dimensionless, the SI unit for the equivalent dose is the same as for absorbed dose, joule per kilogram (J kg-1) and its special name is sievert (Sv).
