flu·ence (H),

(flū'ens),
A measure of the quantity of x-radiation in a beam in diagnostic radiology, either particle fluence, the number of photons passing an aperture of unit cross-sectional area, or energy fluence, the sum of the energies of the photons passing through a unit area. Compare: flux.

flu·ence

(flū'ĕns)
A measure of the quantity of x-radiation in a beam in diagnostic radiology, either particle fluence, the number of photons entering a sphere of unit cross-sectional area, or energy fluence, the sum of the energies of the photons passing through a unit area.

fluence

(floo′ĕns) [L. fluere, to flow]
In radiation oncology, the number of photons per unit area, measured in J/m2 (joules/square meter). Fluence is one of several modifiable factors in the treatment of diseased tissues with radiation.
