A 109Cd K x-ray fluorescence (XRF) system using a point source in a back-scatter geometry is described. The suitability of plaster-of-Paris phantoms as targets for intercalibration standards was evaluated. When the phantom concentrations were measured by inductively-coupled-plasma mass spectrometry (ICPMs), the calculated phantom concentrations… CONTINUE READING
