A complex detector system is being developed for the PANDA experiment at the FAIR accelerator facility in Darmstadt. The electromagnetic process group (EMP) at the Helmholtz institut in Mainz is developing the backward end-cap (BWEC) of this detector and a preliminary version will be used in the PANDA FAIR Phase-0 project to measure the electromagnetic transition form factor of π⁰ at the MAMI-accelerator in Mainz. To verify that the planned setup of the BWEC can withstand the radiation exposure of the experiment without affecting the data acquisition through malfunctions, simulations were performed to estimate the radiation exposure of the whole experiment and of single important components. In the context of these simulations a comparison between the used simulation framework GEANT4 and the prominent FLUKA framework was performed.
