SIMULATION STUDIES OF RADIOGRAPHIC INSPECTIONS WITH CIVA
A new gamma and X-Ray simulation module has been integrated to the CIVA software and completes the already available UT and ECT modules. This module is based on a combination of NDT radiographic modules developed at the CEA LETI and at EDF R&D. Direct radiation is calculated from an analytical approach (ray tracer and Beer-Lambert law for the attenuation) while the scattered radiation is simulated by Monte-Carlo modelling. Different types of sources, gamma or X-rays, and different detectors can be simulated. The X ray module uses the same dedicated Graphical User Interface mutual to UT and ECT techniques. It helps to simulate control of specimens where the geometry can be imported from a CAD tool and also to put in evidence the presence of defects (with canonical geometries or also defined from a CAD tool). In this article, after a description of the different models used, the X-Ray simulation possibilities are illustrated on different practical applications.
