Geant4-based Radioactive Decay模拟验证
Validation of Geant4-based Radioactive Decay Simulation
摘要：
放射性衰变在使用蒙特卡罗模拟的各种各样的应用中受到关注。为了正确地估计这种模拟的质量，需要衰减模拟的准确性的知识。我们提出了一个验证的原始Geant 4放射性衰变模块，它使用每衰变采样方法，和扩展包Geant 4为基础的模拟放射性衰变，除了能够使用重构的每衰变采样，是能够使用统计采样方法。验证是基于使用高纯度锗（HPGe）检测器的校准同位素源的测量;不进行模拟校准。对于所考虑的验证实验，等效模拟精度可以通过预衰减和统计采样来实现。
英文摘要：
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.
