摘要： A method for determining the material of a detected item in objects, especially explosives in luggage, using X-ray diffraction. In this method, wherein scatter radiation deflected at the crystal-lattice structure of the material is measured and compared to characteristic energy spectra or diffraction spectra of various explosives, the absorption by the material influences the X-ray diffraction spectrum, so that information is missing, and inaccurate conclusions may be drawn regarding the material. To improve this method, the primary beam of an X-ray source is used for measuring the absorption. The beam passes through the material, and, from the absorption, an average atomic number of the material is determined, and this additional information is used for the identification of material known by comparing the recorded spectra with diffraction spectra. For this purpose, a collimation/detector arrangement preferably has only one collimator (8) and one detector (9), with the collimator (8) having a conically-expanding circular slot (1), which defines a predetermined diffraction angle, and a central blind bore (1) opening toward the x-ray source. First and second detectors (13, 14) are disposed in the bore to detect lower and higher x-ray energy, respectively.

摘要： A method for detecting X-rays which are separated into individual energy ranges after penetrating an object, as well as to an arrangement for implementing this method. It is known to detect X-rays (FX) by using detection devices (3), consisting of several identically configured detector pairs. The detector pairs in that case consist of a low-energy detector (4) and a high-energy detector (7). As a result, the weakened X-ray beam (FX′) is separated into individual energy ranges following the X-raying of an object (2). This separation is necessary to determine the types of material in the X-rayed object (2). The disadvantage of known detection devices (3) is that an overlapping of the individual energy ranges occurs in the low-energy detector (4), thereby making it impossible to detect the material type with certainty. This problem is avoided by providing for computing out the high-energy shares absorbed in the low-energy detector (4) with the aid of an additional signal. For this purpose, a second low-energy detector (5) is arranged between the first low-energy detector (4) and the high-energy detector (7). An energy spectrum (FX2) that is absorbed in the second low-energy detector (5) is used to obtain the signal to be subtracted.
