论文摘要
建议和验证``基于真实巧合的求和效应''和``简化''方法，用于简单地确定半导体高纯仪（HPGE）检测器系统的光峰效率。方法和校准的$^{60} $ CO放射源可用于委托在潜在的关键事件中使用的任何HPGE检测器。使用此方法的半导体HPGE检测器系统确定的准确性是百分之几（对于本研究中使用的探测器系统，过度简化的$ \ simeq $ 8 \％\％\％\％，$ \ simeq $ 5 \％$ 5 \％用于简化的方法）合理，预期，并且足够预期，并且可以使用来自受影响的人类血液中的中性中的中性中的中性，并且可以使用。此外，如果可以使用建议的方法实验地推导出$^{60} $ 1333 $ 1333 kev $γ$ -Ray线的照片峰值效率，那么在$^{24} $ na iSotope的衰减中，也可以将此效率用于1369 kev $γ$ - 雷线。
``Oversimplified'' and ``simplified'' methods based on true coincidence summing effect used in uncomplicated determination of the photo-peak efficiency of the semiconductor High Purity Germanium (HPGe) detector system are suggested and verified. The methods and calibrated $^{60}$Co radioactive source may be used to commission any HPGe detector to use during potential criticality event. The determined accuracy of the semiconductor HPGe detector system using this method is a few percent (for the detector system used in this study it was $\simeq$8\% for oversimplified and $\simeq$5\% for simplified methods accordingly) reasonable, expected, and good enough to use for estimation of neutron dose from irradiated human blood in a potential criticality event. Moreover, if one can experimentally deduce the photo-peak efficiency for $^{60}$Co 1333 keV $γ$-ray line using the suggested methods, then with a few percent accuracy this efficiency could be also used for 1369 keV $γ$-ray line in the decay of $^{24}$Na isotope.
