Abstract The influence of X-ray tube spectral distribution related to the X-ray tube voltage and target anode on the contribution of scattering effects to the intensity of fluorescence was studied by using some fused disk samples. Three scattering effects were considered. They are coherent scattering effect, incoherent scattering effect and primary fluorescence scattered into the direction of detector respectively. For the fused beads under investigation, the results show that the contributions of coherent scattering effect and the primary fluorescence scattered into the direction of detector decreased with increasing the tube voltage, and the contribution was larger when excited by the X-ray from Cr target than that from Rh target. On the contrary, the contribution of incoherent scattering effect to the intensity of fluorescence increased with increasing the voltage, and was larger when excited by the X-ray from Rh target than that from Cr target. The sum of the contribution of scattering effects to the intensity of fluorescence increased with increasing the voltage, and was larger when excited by the X-ray from Rh target than that from Cr target.
