"Dose Equivalent" (former), or $\textit{Equivalent Absorbed Radiation Dose}$, usually shortened to $\textit{Equivalent Dose}$, is a computed average measure of the radiation absorbed by a fixed mass of biological tissue, that attempts to account for the different biological damage potential of different types of ionizing radiation. The equivalent dose to a tissue is found by multiplying the absorbed dose, in gray, by a dimensionless "quality factor" $Q$, dependent upon radiation type, and by another dimensionless factor $N$, dependent on all other pertinent factors. N depends upon the part of the body irradiated, the time and volume over which the dose was spread, even the species of the subject.

At the point of interest in tissue, $H = DQ$, where $D$ is the absorbed dose and $Q$ is the quality factor at that point.
