HI,

   For example, G4PSFlatSurfaceCurrent/Flux  scores a track at the surface.
The scoring surface is set to -Z surface of the scoring volume, i.e. G4Box's -z surface.
 The direction of track can be specified by the direction.

G4PSFlatSurfaceCurrent::G4PSFlatSurfaceCurrent(G4String name, G4int direction, G4int depth)

  direction = 0     both incoming and outgoing tracks
                    1     only incoming tracks
                     2    only outgoing tracks.

  The current does not take into account the track direction at the surface,
but flux takes into account it by 1/costheta. This factor is multiplied to the scoring value.
