The k 0-based internal mono-standard prompt gamma-ray neutron activation analysis (IM-PGNAA) method was used for compositional analysis of a cement standard provided by the International Atomic Energy Agency as a part of inter-laboratory comparison exercise. The PGNAA was also applied to a local cement sample for comparison purpose. The …

The performance of PGNAA systems can be investigated by using Monte Carlo (MC) codes for neutron-gamma transport calculations. The MC codes can be used to simulate complex systems, which would otherwise be expensive, time-consuming, and occasionally impossible to perform experimentally (Doron et al., 2014).The MC simulations can be achieved …

The performance of a borehole-logging system, based on prompt-gamma-neutron-activation-analysis (PGNAA), for explosive detection was studied by Monte-Carlo simulations. The prompt gamma of nitrogen, which is a constituent of common explosive, was used to identify the unexploded ordnance (UXO). Our results show that the minimum counting time depends …

There are two main options for neutron supply for PGNAA technology. One is a radioisotope, Californium 252 (252 Cf), and the other is a neutron generator system.Such systems deploy PFTNA, using isotopes of hydrogen, deuterium (2 H) and tritium (3 H,) to produce neutrons via a fusion reaction.One distinctive difference when using a neutron generator versus a traditional …

1. Introduction. The prompt gamma-ray neutron activation analysis technique (PGNAA) is a reliable non-destructive technique for determination of elements in large volume samples (Petrovic et al., 1999; Taheri et al., 2017; Nadolski et al., 2018).It is a fast and accurate detection method which is sensitive to most of elements and not influenced by the physical …

PGNAA is the acronym for Prompt Gamma Neutron Activation Analysis. It's a technique that requires a supply of neutrons which can come from either a radioactive source, typically Cf-252, or a neutron generator via Pulsed Fast Thermo Neutron Activation (PFTNA). We pioneered PGNAA and are highly experienced in its successful application in ...

PGNAA Analyser find extensive use in mining and blending operations and possess two notable advantages compared to traditional Analysers: It exhibits a significantly higher tolerance to varying coal types, such as those from different seams. This feature eliminates the need for multiple calibrations, thereby enhancing efficiency.

A detailed discussion of the PGNAA setup for TNC and NIS experiments are provided in Ref. [5, 6].The D(d,n) 3 He reaction in Genie 16 produced neutrons with intensities of about 4.7 (times ) 10 7 n/s and energies of 2.5 MeV. This reaction happened when a deuterium target was impinged upon by deuterons dc beam with an energy of 70 keV and a current of 50 …

In reality, after subtracting the beam background from the prompt $$gamma$$ γ -ray spectrum induced by the irradiated sample with the same time measurement, it still exists the remaining $$gamma$$ γ -ray background induced by the nuclei capturing the thermal neutrons scattered by the sample. This makes it difficult to validate the accuracy of the PGNAA detector …
