“…6A and B MCNP simulations show a 25% higher peak efficiency compared to measurements for the gamma energy 661.7 keV. Others (Korun et al, 1997;Lépy et al, 2001;Gilmore, 2008;Marzocchi et al, 2010) have also observed this discrepancy in Fig. 6A.…”

“…In this technique, the detector ef iciency of using various source dimensions is derived from the known ef iciency for the reference source-to-detector geometry. The ef iciency transfer method is particularly useful due to, its insensitivity to the inaccuracy of the input data, such as the uncertainty of the detector characterization [7,8].…”

Determination of the detector effi ciency using volumetric cylindrical sources is very important in various scientifi c and industrial fi elds, especially in the fi eld of quantitative analysis. To calculate the absolute activity of any sample, the full-energy peak effi ciency (FEPE) of the detector is needed. By applying the effi ciency transfer method, the FEPE of the detector would be determined easily without using the standard sources. This approach depends on two main factors. The fi rst one, is the reference effi ciency of the reference source, which is determined experimentally, and the second one, is the calculation of the effective solid angle ratio between the sample and the reference source geometries. This work introduces an empirical formula for calculating the second factor for using two different sizes of NaI(Tl) detectors. The validity of this empirical formula was successfully demonstrated by comparing the calculating values with the experimental values.

“…There exists extensive literature on the MC method of calibration in gamma-ray spectrometry. It is beyond the scope of this work to review it, however, we provide references to authoritative reviews and inter-comparison studies using MC-based calibrations (by Lépy et al [2], Vidmar et al [3], and Sima [4]). A number of commercial MC codes as well as codes distributed through large research centers are available, in addition to many locally written codes.…”

“…In the original version by Moens et al [5] the transfer of peak efficiency to a new efficiency is accomplished by scaling the former by the ratio of the corresponding "virtual" total efficiencies. Another version, where the scaling factor is the ratio of calculated peak efficiencies [2], can also be considered within the transfer methods group. The assumption of these methods is that the systematic bias in the MC calculations is diminished by taking the ratio of calculated "virtual" total or peak efficiencies.…”
