FLUKA simulations of the target thickness dependence of Cu-K$β$/K$α$ intensity ratios
The numerical Monte-Carlo simulations of Cu-K$α$ and Cu-K$β$ fluorescence lines induced by monoenergetic Am-241 radiation in copper have been presented. The simulations included modeling the K$β$/K$α$ intensity ratios for various thicknesses of copper. The results obtained using the FLUKA code were compared to available experimental and theoretical values. A clear relationship was observed between the simulated K$β$/K$α$ intensity ratios and the sample thickness: as the thickness increased, the K$β$/K$α$ ratio also increased until it reached saturation.
