Scintillators used as active materials of calorimeters plays an important role in particle physics experiments. The optical, scintillating and physical properties of such materials affect performances of calorimeters significantly. In this work, GdTaO4 crystal with very high density was examined as an active material in a homogenous calorimeter with a simulation study. This paper presents the results of the electromagnetic performances of a homogenous calorimeter whose active material is GdTaO4. Calorimeter module were reconstructed in the simulation program in different geometries and energy resolution values for various scintillator-photodetector combinations were obtained as a function of incident gamma beam energies. The predictions of the improvements in energy resolutions with the interested scintillator-photodetector combinations compared to previous studies were noted.
