Abstract

Low-energy x-rays can undergo considerable absorption in the sample material when EDX spectrometry is used in multi-element analysis of aerosol-loaded filters. An expression which corrects for the effects of absorption, based on counting aerosol filters and standards on both sides, is derived. The method is experimental verified by using the absorption of the 60 keV gamraa-ray of 241Am in aluminium and also by comparison with PIXE results for environmental filters.
