Description

The application of prompt gamma neutron activation analysis (PGNAA) to on-line measurement of coal quality is described. Neutrons from 252Cf are thermalized and captured by coal nuclei, and the resulting prompt γ-radiation is detected in a large NaI(T1) scintillation crystal. The measured γ-ray energy spectrum is interpreted through microprocessor-based signal processing to determine the amounts of the major elements in coal together with other useful quantities that can be derived from elemental composition. Measurements with a prototype instrument compare very favorably with conventional laboratory analysis. (author)
