| Abstract: | Summary Elemental concentrations of soil samples collected in the vicinity of a Romanian fertilizer plant were determined by EDXRF
and long half-life INAA. Lower limits of detection, obtained for various elements in soil by EDXRF technique with radioactive
excitation sources (238Pu and 241Am) and a HPGe detector are presented. Spurious effects characteristic for Ge detector X-ray spectrometry are evaluated and
discussed, and methods to overcome this drawback are suggested. Special care was taken to subtract from the spectra the Ge
