Abstract  

Prompt gamma-neutron activation analysis, PGNAA, has been used to determine major and minor elements of bituminous coals. Calibration curves for H, C, N, Cl, Si, Ti, Al, Fe, Ca, Na, K, and S were obtained using six coals of different origin. The correlation coefficients are, in general, greater than 0.9 with the exception of C, N, and K. The -peak intensities were corrected for volume hydrogen content and normalised to the source intensity by using the 2615 keV -line from the (n, n) reaction induced in the lead container of the Cf source. Elemental compositions of new coal samples were determined. In spite of the weak neutron source intensity, the comparison between the elemental concentrations measured by PGNAA and by conventional analysis show good agreement except for N, K, S and Ca.
