Abstract:
In the present work, a dual-energy X-ray radiography system was simulated using MCNPX code. Then, material discrimination curves for graphite, aluminum, steel, and lead materials were obtained using four algorithms, including log-log, R-T, r-θ, and α1-α2. The results show that R-T, r-θ, and α1-α2 algorithms have better performance. Also, due to the less overlap of material discrimination curves for low sample thicknesses, the R-T algorithm can be a better choice for obtaining material discrimination curves in dual-energy radiography systems.
