The numerical simulations of Cu <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>K</mi><mi>α</mi></mrow></semantics></math></inline-formula> and Cu <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>K</mi><mi>β</mi></mrow></semantics></math></inline-formula> fluorescence lines induced by Rh X-ray tube and by monoenergetic radiation have been presented. The copper <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>K</mi><mi>β</mi><mo>/</mo><mi>K</mi><mi>α</mi></mrow></semantics></math></inline-formula> 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 <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>K</mi><mi>β</mi><mo>/</mo><mi>K</mi><mi>α</mi></mrow></semantics></math></inline-formula> intensity ratios and the copper content of the Ag–Cu alloy: as the Cu content increases, the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>K</mi><mi>β</mi><mo>/</mo><mi>K</mi><mi>α</mi></mrow></semantics></math></inline-formula> coefficient decreases. The results can play role in elemental material analysis, especially in archaeometry.
