Definition

EN

differential quotient of radiant energy R (radiant energy <ionizing radiation>) incident on a sphere of cross-sectional area (cross section <atomic physics>) a with respect to that area:

Ψ = d R d a
FR

quotient différentiel de l'énergie rayonnante R (radiant energy <ionizing radiation>) incidente sur une sphère ayant une aire de section efficace (cross section <atomic physics>) a par rapport à cette aire:

Ψ = d R d a

Notes

EN

In report 85a of the ICRU a definition with an equivalent meaning is given as:

The energy fluence, Ψ , is the quotient of d R and d a , where d R is the radiant energy incident on a sphere of cross-sectional area d a :

Ψ = d R d a

See also cls-0.3.

FR

Le rapport 85a de l'ICRU, donne une définition ayant une signification équivalente:

La fluence énergétique, Ψ , est le quotient de d R par d a , où d R est l'énergie rayonnante incidente sur une sphère ayant une aire de grand cercle d a :

Ψ = d R d a
