FLUKA Simulations of Kβ/Kα Intensity Ratios of Copper in Ag–Cu Alloys

The numerical simulations of Cu [Formula: see text] and Cu [Formula: see text] fluorescence lines induced by Rh X-ray tube and by monoenergetic radiation have been presented. The copper [Formula: see text] intensity ratios for pure elements as well as for Ag–Cu alloys have been modeled. The results obtained by use of the FLUKA code, based on the Monte-Carlo approach, have been compared to available experimental and theoretical values. A visible relationship was found between the simulated [Formula: see text] intensity ratios and the copper content of the Ag–Cu alloy: As the Cu content increases, the [Formula: see text] coefficient decreases. The results can play role in elemental material analysis, especially in archaeometry.
