Description
Summary:A real coaxial HPGe detector, and two lanthanide scintillation detectors have been modeled and characterized by means of Monte Carlo simulation, as part of a project to develop new techniques instrumentation to be used for the primary standardization of high intensity gamma source facilities. The simulation of .sup.152Eu spectra with MCNP 6.2 was used to characterize the detectors in full energy peak efficiency, and coincidence-summing corrections. The .sup.152Eu source, has a complex decay, one by electron conversion, and second beta decay (-[beta]), and in return the spectrum of .sup.152Eu has a lot of peaks affected by the True Coincidence Summing, so any experimental or simulated data needs correction for this effect either during the simulations or after. For post processing of gamma-ray spectra, we used EFFTRAN and GESPECOR software for corrections factors for HPGe, LaBr.sub.3(Ce), LaCl.sub.3(Ce) detectors. This work also made a comparison on how the two software's will perform.
