First thing, a minor question : do you really want to apply your EMFCUT
specifications only to materials 2.0 to 7.0 ?
EMFCUT assignment is not done by regions, but by materials.
I ran FLUKA with your input.
Result for usrtrack with ustsuw treatment and multiplied by the energy
bin : 1,41*10e-4 photons/cm²/incident photon
Result for usrbin with usbsuw and pawlevbin treatment : ~10e-3
The two methods give tracklengh fluence (cm/cm3/primary), but not the
same results, it is true.
It depends on what you wanna calculate : the total fluence (or the
fluence versus energy bins in case of several energy bins)
in a given region (usrtrack) or the "spatial" (easily plotted with the
associated tools) fluence in a binning of your choice (usrbin).
Here, since you want to score what happens in your detector (this is
what I assumed), aka a defined region, I would rather use USRTRACK.
Hope it helps.

If I understand well, both these cards should give same result, USRBIN and (USRTRACK * Energybin). But in my simulation, these are not the same. I am sending the input file for reference.
