Abstract

Based on the test object and the given data from the detectors, a set of formulas connecting the characteristics of digital radiography systems with the parameters of the X-ray radiation source, is checked. The obtained formulas can give a rational choice of the source and the X-ray detector for a non-destructive test. A series of calculations for the digital radiography characteristics of systems based on the CdWO4 panel detectors with the 0.3 mm thickness for medium and high X-ray energies were carried out. A series of experiments were carried out to determine the X-ray attenuation rate with the maximum energies of 4.5 MeV and 9 MeV for steel plates with a mass thickness from 20 g/cm2 to 80 g/cm2. A comparison of the experimental and calculated data on the attenuation rate showed good convergence for the range of mass thicknesses of the test object fragments. The calculation results and the results of experimental studies prove the correctness of the proposed method for calculating and evaluating the basic parameters of digital radiography systems under the condition of rigid slit collimation of X-ray radiation for inspection of large objects from highly scattering materials.
