Abstract
The PIXE method was applied to the analysis of trace elements in scalp hair using two methods for target preparation. In the first method eight hair strands each of nearly circular cross-section and having approximately the same diameter were selected and placed on an aluminum frame. In the second method a given mass of hair was dissolved in nitric acid and a known amount of strontium was added to the solution and dripped onto a membrane filter using a micropipette. The results for the concentrations of trace elements in hair obtained by the two methods are compared and several aspects of the analysis are discussed.
