Dera Lewis,
no, FLUKA does not incorporate radiative Bhabha,
it does incorporate "standard" Bhabha positron-electron scattering.
ay I ask you some more detail on your problem? Indeed, one would expect a
very small energy loss in 0.01RL of Beryllium.

I am simulating a 45 GeV positron beam hitting a thin Be target, approx.
0.01 RL I’m plotting the e+ track-lengh as function of energy using
USRTRACK. I find that the e+ beam energy quickly degrades which shows up
in the track-length quickly shifting toward lower energy e+. Since
bremsstrahlung energy loss is negligible for this thin radiator, my
question is does FLUKA incorporate radiative bhabha scattering from a
positron interacting with an atomic electron to cause the e+ to rapidly
lose energy?
