“…This yields evidence that the G4AtomicDeexcitation process and its underlying EADLbased data library are at least partially responsible for the large intensity deviation. This observation is in accordance with the findings in [10] and [16].…”

Abstract-Radioactive decays are of concern in a wide variety of applications using Monte-Carlo simulations. In order to properly estimate the quality of such simulations, knowledge of the accuracy of the decay simulation is required. We present a validation of the original Geant4 Radioactive Decay Module, which uses a per-decay sampling approach, and of an extended package for Geant4-based simulation of radioactive decays, which, in addition to being able to use a refactored per-decay sampling, is capable of using a statistical sampling approach. The validation is based on measurements of calibration isotope sources using a high purity Germanium (HPGe) detector; no calibration of the simulation is performed. For the considered validation experiment equivalent simulation accuracy can be achieved with per-decay and statistical sampling.

“…The original validation process applied in several tests (e.g. [28], [29], [30], [31], [41], [42], [43], [44], [45], [25], [50] [51]) has gone into various refinements since its first development described in [50]. It consists of a two-stage process: the first stage encompasses goodness of fit testing, while the second deals with the analysis of categorical data derived from the outcome of the first stage.…”

“…The failures of EPDL-based cross sections at reproducing experimental data mostly concern test cases close to absorption edges. Issues about the accuracy of related calculations of atomic binding energies collected in EADL (Evaluated Atomic Data Library) [267] were documented in [22]; as discussed in section VI-B, experimental measurements in these regions are delicate, as realistic estimates of experimental uncertainties are prone to be affected by systematic effects deriving from the experimental environment.…”

Several total and partial photoionization cross section calculations, based on both theoretical and empirical approaches, are quantitatively evaluated with statistical analyses using a large collection of experimental data retrieved from the literature to identify the state of the art for modeling the photoelectric effect in Monte Carlo particle transport. Some of the examined cross section models are available in general purpose Monte Carlo systems, while others have been implemented and subjected to validation tests for the first time to estimate whether they could improve the accuracy of particle transport codes. The validation process identifies Scofield's 1973 non-relativistic calculations, tabulated in the Evaluated Photon Data Library (EPDL), as the one best reproducing experimental measurements of total cross sections. Specialized total cross section models, some of which derive from more recent calculations, do not provide significant improvements. Scofield's non-relativistic calculations are not surpassed regarding the compatibility with experiment of K and L shell photoionization cross sections either, although in a few test cases Ebel's parameterization produces more accurate results close to absorption edges. Modifications to Biggs and Lighthill's parameterization implemented in Geant4 significantly reduce the accuracy of total cross sections at low energies with respect to its original formulation. The scarcity of suitable experimental data hinders a similar extensive analysis for the simulation of the photoelectron angular distribution, which is limited to a qualitative appraisal.
