We have modelled the hard X-ray background expected for a high-altitude balloon flight of the Energetic X-ray Telescope Experiment (EXITE2), an imaging phoswich detector/telescope for the 20--600 keV energy range. Photon and neutron-induced contributions to the background are considered. We describe the code and the results of a series of simulations with different shielding configurations. The simulated hard X-ray background for the actual flight configuration agrees reasonably well (within a factor of ∼ 2) with the results measured on the first flight of EXITE2 from Palestine, Texas. The measured background flux at 100 keV is ∼ 4 × 10-4 counts cm-2 s-1 keV-1.
