OPTIMIZATION OF THE X-RAY DETECTOR SCATTERED FROM THE TEST OBJECT
(pp. 32-41)

Abstract. Various geometries and materials of radiation detectors are considered. The efficiency of detection of scattered radiation is estimated by means of inorganic and organic scintillation detectors with various effective atomic numbers. It gives calculations and experiments to determine the signal-to-noise ratio for scanning systems with registration of the radiation beam reflected from the object were carried out taking into account dynamic blurring. Methods for manufacturing detectors that increase the collection efficiency of secondary lowenergy quanta formed in the body of the scintillator and reduce the overall dimensions of the photo electron multiplier + scintillator structure are considered. The conditions for the reduction of dynamic blurriness are formulated. The conditions for achieving the maximum of the efficiency of detection of light photons are determined and the designs are proposed for their practical realization.

Keywords: non-destructive testing, measurements, scattered radiation, X-ray inspection.
