fluence

Steady outward emanation

Fluence is a technical term in physics measuring the total energy or number of particles passing through a given area over time—essentially accumulated exposure.

In laser applications, fluence determines tissue damage thresholds; in radiation, it quantifies dose delivery.

Outside science, the word is rare, though it appears as a root in influence and affluence, both carrying the original Latin sense of flowing.
