H_T = \displaystyle \sum_{R} w_RD_{R,T}

where D<submath>D_{R,T}</submath> is the mean absorbed dose from radiation <math>R </math> in a tissue or organ <math>T</math>, and w<submath>Rw_R</submath> 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).

H_T = \displaystyle \sum_{R} w_RD_{R,T}

 where <math>w_R</divmath>where 𝑤𝑅 is the radiation weighting factor for radiation type <math>R</math>, and 𝐷𝑅<math>D_{R,𝑇 T}</math> is the organ absorbed dose from radiation type <math>R </math> in a tissue or organ 𝑟𝑇 <math>r_T</math> of the Reference Adult Male or the Reference Adult Female. As 𝑤𝑅 <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).
