“…The full energy peak in the simulated spectra was treated as a Gaussian peak whose resolution (∆ ) i.e. Full Width at Half Medium ( ) was derived from the measured photopeak [12]. This broadening is required to take into account the statistical fluctuations in each step during pulse creation process.…”

Due to their attractive performances, inorganic scintillators such as NaI(Tl) detectors are widely used in the field of gamma-ray spectrometry where knowledge of detector efficiency is a key factor for successful quantitative  ray analysis. Monte Carlo simulations using MCNP code have been performed in order to evaluate absolute efficiency of NaI detectors. Two mathematical models were constructed for the NaI crystal: 7.62cm x 7.62cm cylindrical NaI and 7.62cm diameter spherical NaI. Detector efficiency was calculated for both NaI detectors in the photon energy range from 60 keV to 2750 keV. Simulation results were compared to experimental efficiency data.

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.
