Abstract
Prompt gamma neutron activation analysis (PGNAA) is a non-destructive online measurement nuclear analysis method. With its unique advantages, it has been widely used in online analysis of industrial materials such as coal, cement, and minerals in recent years. However, there are many kinds of literature on PGNAA in the field of industrial materials detection, and there are still a few concluding articles. To this end, based on the principle of PGNAA online analysis, the status quo and development of the real-time online detection of industrial material components in the field are reviewed and discussed by consulting a large number of domestic and foreign PGNAA related literature and data, to facilitate the reference of relevant scientific researchers.
Highlights
Industrial material composition real-time online detection technology is a real-time and accurate online analysis and detection technology for material composition in the process of industrial feeding and batching
The use of the prompt gamma neutron activation analysis (PGNAA) method for the on-line analysis of the total element composition of industrial materials has been a hot spot in the field of nuclear detection and analysis in recent years [62]
The real-time online detection system of industrial material composition is mainly based on the Prompt gamma neutron activation analysis (PGNAA) technology of isotope neutron source or neutron generator
Summary
Industrial material composition real-time online detection technology is a real-time and accurate online analysis and detection technology for material composition in the process of industrial feeding and batching. NAA technology can be used for non-destructive measurement with high sensitivity and good accuracy, but it cannot be used for real-time online analysis It is more powerless for the determination of some light elements (such as H, B, N, P, etc.) [1]. Prompt Gamma Neutron Activation Analysis (PGNAA) is a non-destructive, efficient, multi-element online nuclear analysis technology [5] In principle, it can measure most of the elements on the periodic table [6], especially in the analysis of elements with large (n, γ) reaction cross-sections (B, Cd, Gd, H, etc.), its sensitivity is high, and it is usually used as a supplement to conventional analysis, the analysis of light elements in large samples is the only method [7]. In the conclusion part, it summarizes the industrial application of PGNAA technology
