摘要： THIS INVENTION relates to a method of or system for detecting presence of diamond in an object. The method comprises receiving classification data associated with photons emitted from object as a result of positron annihilation due to irradiation of the object with photons of a predetermined energy at which giant dipole resonance (GDR) occurs due to a nuclear reaction between the photons and carbon. The method then comprises the step of determining whether or not the object is potentially a diamond or diamondiferous by processing the received classification data with a trained machine-based learning classifier. The system typically implements the method described herein.

摘要： The sorting method includes: an X-ray inspection step of irradiating a resin piece with X-rays including a first X-ray and a second X-ray having respective energy ranges different from each other and measuring a first transmission intensity which is an intensity of the first X-ray transmitted through the resin piece and a second transmission intensity which is an intensity of the second X-ray transmitted through the resin piece; a first determination step of making a determination as to whether the resin piece is a candidate for a useful resin piece, using the first transmission intensity; and a second determination step of making a determination as to whether a resin piece identified as a candidate for a useful resin piece in the first determination step is a useful resin piece, using a differential value obtained from the first transmission intensity and the second transmission intensity.

摘要： Disclosed herein is the use of differences in x-ray linear absorption coefficients to process ore and remove elements with higher atomic number from elements with lower atomic numbers. Use of this dry method at the mine reduces pollution and transportation costs. One example of said invention is the ejection of inclusions with sulfur, silicates, mercury, arsenic and radioactive elements from coal. This reduces the amount and toxicity of coal ash. It also reduces air emissions and the energy required to clean stack gases from coal combustion. Removal of said ejected elements improves thermal efficiency and reduces the pollution and carbon footprint for electrical production.

摘要： A laser-based mono-energetic gamma-ray source is used to provide a rapid and unique, isotope specific method for sorting materials. The objects to be sorted are passed on a conveyor in front of a MEGa-ray beam which has been tuned to the nuclear resonance fluorescence transition of the desired material. As the material containing the desired isotope traverses the beam, a reduction in the transmitted MEGa-ray beam occurs. Alternately, the laser-based mono-energetic gamma-ray source is used to provide non-destructive and non-intrusive, quantitative determination of the absolute amount of a specific isotope contained within pipe as part of a moving fluid or quasi-fluid material stream.
