Radiation dosimetry

Measurement or calculation of energy imparted by ionizing radiation, together with explicitly specified weighting conventions. Absorbed dose, equivalent dose and effective dose are different quantities.

Table of contents

Effective dose ( $E = \sum_{T} w_{T} H_{T}$ )

A tissue weighting factor weighted sum of equivalent doses. Its unit is the sievert.

Tissue weighting factor ( $w_{T}$ )

A dimensionless weight in effective dose; the weights over the reference tissues sum to one.

Equivalent dose ( $H_{T} = \sum_{R} w_{R} D_{T, R}$ )

A radiation weighting factor weighted sum of mean absorbed doses for a specified organ or tissue. Its unit is the sievert.

Radiation weighting factor ( $w_{R}$ )

A dimensionless factor used to convert a specified radiation component's absorbed dose into its contribution to equivalent dose.

Absorbed dose ( $D = d \overline{ε} / d m$ )

Mean energy imparted by ionizing radiation per unit mass; its unit is the gray.
