TL;DR: In this paper, high energy neutron irradiation of the sample, measurement of the thermal neutron flux in the sample and monitoring the gamma radiation from the sample at energies of (a) 1.78 MeV and (b) 0.844 MEV and/or 1.015 MeV.

TL;DR: In this article, the prompt gamma neutron activation analysis technique was used for the determination of sulphur in coal seams and overburden rock, and the logging tool employed a 3 μg 252 Cf neutron source and a 50 mm dia × 100 mm BGO detector.

TL;DR: In this paper, the authors used spectrometric gamma-gamma methods for borehole logging measurements of coal ash content carried out in rough dry boreholes, and achieved an accuracy of 2.2% for coal ash contents between 7 and 28%.

TL;DR: In this article, a number of bulk analysis techniques developed particularly for the mining industry by the CSIRO Division of Mineral Physics are reviewed, which are obtained directly from 3-30 kg samples without further sample preparation, or from material located on conveyor belts.

TL;DR: In this paper, a fast neutron activation technique was developed for the determination of SiO/sub 2/ in 30-kg samples of iron ore of -6-mm particle size, if particular care is taken to minimize the thermal neutron flux in the sample.
