Testing efficiency transfer codes for equivalence

Efficiency calibration of a HPGe detector for the measurement of the primary coolant

“…There are codes which accomplish the efficiency transfer for cray spectrometry [14,15]. However, in order to obtain an accurate energy-efficiency curve over the high energy range, standard sources were used to perform the efficiency calibration of the detection system in this work.…”

Characterization of coal and charcoal by alpha-particle and gamma-ray spectrometry

“…This procedure saves both time and resources since no sample-specific experimental calibration is needed. Moreover, it has the advantage that many potential inaccuracies in the detector model cancel out to a large degree in the calculated ratio obtained by Monte Carlo simulation, making it possible to work directly with the non-optimized detector data supplied by the manufacturer (Vidmar et al, 2010). For this calculation, we used the well-known Monte Carlo simulation code DETEFF (Cornejo Díaz and Jurado which has been widely used for the evaluation of coaxial gamma-ray detector efficiencies.…”

Photon detection efficiency of a germanium semiconductor spectrometer

“…In such cases, calculation methods for determining the photon detection efficiency are used [2], which also allow one to take the cascade summation effects [3] into account for complex radionuclide decay schemes. Because of the necessity of measuring low activities in problems of radiation monitoring of the environment and physical investigations on the IHEP accelerators, a software package was developed for cal culating the photon detection efficiency for an arbi trary geometry of samples and the experimental data correction for coincidences due to the cascade sum mation.…”
