Comprehensive Monte-Carlo Simulator for Industrial X- ray Radiography in Non-destructive Testing

In the present investigation, a monte-carlo (MC) simulator for conventional industrial radiography has been introduced. Acquiring the acceptable precise simulated radiographic image respecting of the object geometrical shape, atomic number, density etc. was the main purpose of this study. Although there are some commercial softwares available for this purpose, all of these softwares have been using analytical or finite element methods for simulating the radiographic images. They don’t influence the complicated random behavior of X-ray photons due to not affecting the photons’ cross-sections with different matters in different energies. We have utilized a monte-carlo code MCNPX2.7e for transporting x-ray photons. X-ray spectrums have been derived by another monte-carlo code and its output has been put as an input in the second monte-carlo code for energy distribution of the geometrical pair code. MC Results validated by experimental data and demonstrated very accurate agreement. Final outcomes showed our technique for simulating radiographic testing can strongly be accurate even for exact simulations. Unlike the other models, our monte-carlo modeling observations showed it is able to measure and able to map the scattered photons as well as primary ones. It is very crucial if we want to investigate the effective parameters on our radiographic testing in order to optimize them before implementing experimental set-up.
