Determination of Heavy Metals and Fluorine in Airborne Particulate Matter in an Indoor Environment by Simultaneous Use of PIXE and γ-Ray Detection

The current rapid development within work-environment research has created a considerable demand among industrial hygienists for suitable analytical methods. PIXE (particle-induced X-ray emission analysis), which was introduced in Lund in 1970, has been shown to be a feasible method for use in studying the elemental composition of aerosols. However, in some work environments, fluorine, an element not suitable for PIXE analysis, is hygienically of considerable interest. This paper discusses the possibility of combining PIXE with a nuclear method for the simultaneous quantitative determination of fluorine.
