CaMoO₄ crystal is a material candidate forthe scintillation detector and double beta decay experiment to determinea neutrino mass. The objective of this work is to analyze the response function of CaMoO₄ using Monte Carlo GEANT4 simulation. Penelope-low energy method was used as an interaction type for the electromagnetic process. The simulation results show that the presence of the photopeak energies of gamma ray from Cs-137, Co-60 and K-40 sources can be identified and observed in the energy 0.662 MeV, 1.17 MeV, 1.33 MeV and 1.5 MeV. The photoelectric cross section interaction of CaMoO₄ is lower than NaI(Tl), but in other hand the incoherent cross section is vice versa.
