The prompt gamma-ray neutron activation analysis (PGNAA) is a significant technique for determining the quantities of a variety of elements in natural materials, whether online or in situ, regardless of their chemical compounds. This study focused on evaluating the performance of a portable PGNAA setup based on a Genie 16 DD neutron generator to determine the minimum detectable concentration (MDC) of nickel in soil samples. Two separate reaction mechanisms were used to activate the samples. A CeBr detector was used to detect nickel gamma rays at 1331 and 1454 keV caused by neutron inelastic scattering, as well as those at 8553 and 8998 keV emitted following thermal neutron capture activations. The obtained MDC values for both reaction channels have improved as a result of the research.
瞬发伽马射线中子活化分析（PGNAA）是一种重要的技术，可用于确定天然材料中各种元素的数量，无论是在线还是原位，无论其化合物如何。本研究重点评估了基于 Genie 16 DD 中子发生器的便携式 PGNAA 装置的性能，以确定土壤样品中镍的最小可检测浓度（MDC）。使用两种不同的反应机制来激活样品。使用 CeBr 探测器来检测由中子非弹性散射引起的在 1331 和 1454 keV 处的镍伽马射线，以及由热中子俘获激活后发射的在 8553 和 8998 keV 处的镍伽马射线。由于这项研究，两种反应通道的获得的 MDC 值都得到了改善。
