The application of prompt-gamma neutron activation analysis to borehole
The PGNAA technique was tested for the in-situ determination of ash, Fe, Si, Al and density of coal seams in water-filled boreholes. The technique is also able to determine in situ the deformation temperature of coals for which a correlation exists between the deformation temperature and the percentage of Al, Si and Fe present in coal. The logging tool employed a …

Once the system has been calibrated, the results are available right after completion of logging operations at a given borehole. There are relatively few reports describing the application of PGNAA logging for in-borehole determination of copper grade (Nargawalla et al., 1977; Moxham et al., 1972). Since then, significant progress has been ...

Material Analysis: Prompt-Gamma Neutron Activation Analysis (PGNAA
PGNAA systems use Cf-252 neutron sources to detect the presence and concentration of chlorine and hydrogen in iron and ore smelting. They are also used to detect copper, gold, silver, and other metals and elements at mining sites. Data obtained with PGNAA systems are critical to the process of blending the feed of raw materials during milling.

Detection of unexploded ordnance by PGNAA based borehole-logging
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 …
