Extended Definition: FLUENCE

Fluence

In physics, fluence or integrated flux is defined as the number of particles that intersect a unit area . Its units are m^–2 (number of particles per meter squared). In particular, it is used to describe the strength of a radiation field, in which case the unit used is J/m². It is considered one of the fundamental units in dosimetry.

It has two equivalent definitions:

1. Imagine that an infinitesimal sphere of cross sectional area da is impinged upon by dN particles of a certain type. Then, the fluence is

$\Phi = \frac{{\rm d} N}{{\rm d} a}$ .

2. Using the same image of a small sphere as above,

$\Phi = \frac{\sum {\rm d \ell} }{{\rm d} V}$ ,

where $d V$ is the infintesimal volume and $\sum {\rm d \ell}$ is the sum of all the path lengths of the particles that transverse the volume.
