P. Arikan et al., DETERMINATION OF HIGH-Z MATERIALS IN LOW-Z MEDIUM BY X-RAY-SCATTERINGTECHNIQUES, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 95(1), 1995, pp. 82-86
The quantitative determination of high-Z elements (mineral matter and
ash) in low-2 medium (coal) by X-ray scattering techniques is presente
d. The X-ray fluorescence method and backscattering techniques were us
ed to examine 40 well characterized domestic lignite samples from diff
erent deposits. The ash content in the coal samples was found to vary
between 6 and 25%. Correlations between the Rayleigh/Compton intensity
ratio (R/C) and ash and between R/C and mineral matter of coal were d
epicted with linear and quadratic functions.
