LAUSR

A workspace is created within the geant4 Application for Tomographic Emission (gate) software toolkit for radiographic nondestructive testing (NDT) simulations. The workspace contains models for X-ray and gamma ray emissions, test sample geometries, radiation interaction with the test sample, and image receptors to afford a radiographic NDT setup. The setup is then evaluated by simulating radiographic testing (RT) of stainless-steel step-wedges and a carbon steel flawed welded plate. The results are validated by comparing a simulated step-wedge image to an experimental radiograph. The workspace can be advantageous to the industrial radiography specialists who are unfamiliar with medical imaging software. Running the simulation does not require working knowledge of gate; the open-source software toolkit.
