Application of the Monte Carlo method for the efficiency calibration of CsI and NaI detectors for gamma-ray measurements from terrestrial samples

GEANT4 Calibration of Gamma Spectrometry Efficiency for Measurements of Airborne Radioactivity on Filter Paper

“…The average of the reported biases between experimental and simulation output were 0.7 % for a water-filled Marinelli sample and 0.6 % for a polyethylene filter paper. Also available in the literature is the work of Baccouche et al (2012), where GEANT4 was used to simulate the efficiency of CsI and NaI detectors for the energy range of 662-2,614 keV. While this study used a random sampling algorithm for its Monte Carlo simulations as discussed above, the Hurtado et al (2004) work used the variance reduction technique, in which incoming photons were forced to interact within geometric boundaries.…”

A study of the effect of Al 2 O 3 reflector on response function of NaI(Tl) detector

“…This technique involves the use of FT8 GEB in MCNP5 and the calculation of the 5 full width at half maximum (FMHM) height of the Gaussian peak. The FWHM function is defined by the following equation (Amgarou et al, 2009, Baccouche et al, 2012, Kovaltchouk et al, 2011:…”

Peak shifted properties of the “low background NaI(Tl) detectors”: An experimental study of response function behavior in different temperature and acquisition time

“…NaI(Tl) scintillator is a high efficiency device in detection and identification of weak gamma sources with a simple decay scheme, when the energy resolution is not an issue (Baccouche et al, 2012). Also, in the cases that energy resolution are important, the use of NaI(Tl) is not restricted.…”
