The GADAST detector array, developed within the EXPERT project of the Super-FRS Experiment Collaboration at FAIR, is designed for detecting light charged particles and *g rays emitted in the de-excitation of daughter nuclei born in proton and neutron radioactive decays (e.g. &sup(30)Ar *> 2p + &sup(28)S ∗ ). In this work, 32 CsI(Tl) GADAST modules were tested and characterized in terms of energy resolution and light-output non-uniformity to verify their compliance with technical requirements. The energy resolution for irradiation by uncollimated 662 keV γ rays ranges from 7.90% to 10.82%, with a median value of 9.91%, while the light-output non-uniformity along the length of the crystal for irradiation with collimated source varies from 0.34% to 3.66%, with a median value of 1.42%. GADAST specific functionality such as light output non-uniformity parametrization and pile-up simulation was implemented in the ExpertRoot framework based on GEANT4 and FairRoot. The implementations were validated using Monte Carlo simulation of the test measurements. The specific features of a typical experimental spectrum were reproduced with good agreement in the simulations.
