The Prompt Gamma Neutron Activation Analysis (PGNAA) has developed considerably for bulk-materials analysis. Taking advantage of the representativity of PGNAA owing to the large mass of material investigated, companies have built commercial systems for the real-time analysis of materials for raw mix preparation [1] such as phosphate [2], …

Nuclear borehole logging is practically the only technique that has the capacity for providing quantitative in-situ coal quality information in real time. The SIROLOG gamma–gamma and neutron–gamma (PGNAA) borehole logging procedures have been providing vital characteristics of the coal seams at Callide coalfields since 1993.

In the capture process, the thermal neutron enters the nucleus, and produces an unstable compound nucleus, which decays by emission of one or more γ-rays.These γ-rays are characteristic of the particular nucleus and are normally named neutron capture γ-rays.The neutron capture technique is commonly used in nuclear borehole logging and on-stream …

More recently, borehole logging using PGNAA is also receiving considerable attention as a practical tool for in situ elemental analysis for the coal and mineral industries (Clayton and Wormald, 1983; Charbucinski et al., 1988; Pinault, 1988). For the former, the concentrations of S, Cl and the ash contents as indicators of the coal quality, as ...

Currently, exploring the resources near the earth's surface requires developing the PGNAA technique for borehole logging purposes, where information is needed to investigate the rocks or soils surrounding the hole. In this vein, the majority of recent articles [24,25] have focused on Monte Carlo simulations. Hence, measurements employing ...
