where 𝑤𝑅 is the radiation weighting factor for radiation type R, and 𝐷𝑅,𝑇 is the organ absorbed dose from radiation type R in a tissue or organ 𝑟𝑇 of the Reference Adult Male or the Reference Adult Female. As 𝑤𝑅 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 130]], 2015)

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