Definition

expectation value of the energy imparted (energy imparted):

\bar{ε} = R_{in} - R_{out} + \sum Q

where

$R_{in}$ :: is the radiant energy (radiant energy <ionizing radiation>) of all those charged and uncharged ionizing particles that enter the volume,

$R_{out}$ :: is the radiant energy of all those charged and uncharged ionizing particles that leave the volume, and

$\sum Q$ :: is the sum of all changes of the rest energy (rest energy) of nuclei and elementary particles that occur in that volume

espérance mathématique de l'énergie communiquée (energy imparted) :

\bar{ε} = R_{in} - R_{out} + \sum Q

où

$R_{in}$ :: est l'énergie rayonnante (radiant energy <ionizing radiation>) de toutes les particules ionisantes chargées et non chargées entrant dans le volume;

$R_{out}$ :: est l'énergie rayonnante de toutes les particules ionisantes chargées et non chargées sortant du volume; et

$\sum Q$ :: est la somme de toutes les variations de l'énergie au repos (rest energy) des noyaux et des particules élémentaires survenant dans ce volume

Notes

Sometimes, it has been called the integral absorbed dose.

$Q > 0$ means decrease of rest energy;

$Q < 0$ means increase of rest energy.

Elle a parfois été appelée dose absorbée intégrale.

$Q > 0$ signifie une diminution de l'énergie au repos ;

$Q < 0$ signifie une augmentation de l'énergie au repos.
