Coincidence-summing correction equations in gamma-ray spectrometry with p-type HPGedetectors

Calibration of HPGe detectors using certified reference materials of natural origin

“…The contribution of terms (coincident energies) having coefficients of less than five per thousand is not considered since their contribution in the correction factor is generally on the order of fractions of a percent. The correction equations are found to be comparable with those calculated in other studies [26][27][28], within few percent on the coefficients terms. The ''apparent'' full energy peak efficiency (e p ) and total efficiency (e t ) (Fig.…”

“…The uncertainties of components are assessed either by Type A or by Type B evaluations. Type A evaluation is based on a statistical evaluation of measurement data, as in the case of the counting uncertainty which is normally evaluated Terms for c-KX-ray coincidence summing are taken from bibliography [26][27][28] J Radioanal Nucl Chem according to the Poisson statistics. Type B evaluation is performed by any other method, e.g.…”

Calculation of coincidence summing in gamma-ray spectrometry with the EGS5 code

“…Expressions reported by Tomarchio and Rizzo (Tomarchio and Rizzo, 2011) were used for 22 Na, 24 Na, 60 Co, 88 Y, 110m Ag, and 134 Cs. The results are summarized in Table 1.…”

“…Expressions (Tomarchio and Rizzo, 2011) of the coincidence summing correction factor F(E) for 60 Co, 88 Y, 110m Ag, and 134 Cs. εpðEÞ and εt ðEÞ show the full-energy peak efficiency and the total efficiency for γ-rays with an energy E, respectively.…”

Coincidence summing corrections in HPGe gamma-ray spectrometry for Marinelli-beakers geometry using peak to total (P/T) calibration

“…Thus, for added accuracy in gamma-ray spectroscopy, the corrections for the coincidence summing effects are highly desirable. Several algorithms and empirical equations have been developed in the literature to take into account these effects (Arnold & Sima, 2004;Blaauw & Gelsema, 2003;Dias, Koskinas, & Takeda, 2002;Tomarchio & Rizzo, 2011;Vidmar, Kanisch, & Vidmar, 2011) The peak-to-total ratio (P/ T) is an established method for coincidence summing effects corrections in the gamma-ray spectrometry field (ANSI, 1999). However, the method is not used in routine measurements due to the elaborate work involved in its implementation, especially for close geometry measurements (Lee, Park, & Woo, 2008).…”
