Definition

quotient of the mean energy (ISO 80000-4: Mechanics) $d E_{Δ}$ lost by the charged particles due to electronic interactions in traversing a distance (ISO 80000-3: Space and time) $d l$ , minus the mean sum of the kinetic energies in excess of $Δ$ of all the electrons released by the charged particles and $d l$ :

L_{Δ} = \frac{d E_{Δ}}{d l}

quotient de l'énergie (ISO 80000-4: Mechanics) moyenne $d E_{Δ}$ perdue par les particules chargées en raison des interactions électroniques le long d'un parcours de longueur $d l$ (ISO 80000-3: Space and time), diminuée de la somme moyenne des énergies cinétiques dépassant $Δ$ de tous les électrons libérés par les particules chargées, par $d l$ :

L_{Δ} = \frac{d E_{Δ}}{d l}

Notes

This quantity is not completely defined unless $Δ$ is specified, i.e. the maximum kinetic energy of secondary electrons whose energy is considered to be "locally deposited." $Δ$ may be expressed in $unitsml(eV)$ .

Note that the abbreviation LET specifically refers to the quantity $L_{\infty}$ mentioned in the remark to quality factor <ionizing radiation>.

Cette grandeur n'est pas complètement définie, sauf si $Δ$ est spécifiée, c'est-à-dire l'énergie cinétique maximale des électrons secondaires dont l'énergie est considérée être «transmise localement». $Δ$ peut être exprimée en électronvolts.

Noter que l'abréviation LET se rapporte spécifiquement à la grandeur $L_{\infty}$ mentionnée dans la remarque en quality factor <ionizing radiation>.
