ABSTRACT:
A system and method of rapidly obtaining quantitative information as to the elemental constituents of coal, particularly the oxygen and sulfer content thereof. The system makes use of the photonuclear interaction to produce the desired radioactivity in the coal constituents. The above mentioned interaction is induced by high energy x-rays from a suitable electron accelerator. The induced radioactivity manifests itself by the emission of characteristic gamma rays among other things. These gamma rays are detected by conventional energy sensitive gamma-ray detectors such as germanium or sodium iodide crystals. The resultant signals are sorted and analyzed to provide the desired information.
