Abstract

Environmental samples have been analysed by measuring the X-rays induced by proton bombardment, if necessary by addition of an internal standard. Lighter elements were analysed more suitably by protons of energy 200 keV, because the background in the lower region of emitted photon energies was considerably less than with 3.5 MeV protons. A wide range of elements in soil was analysable by using protons of both these energies. Analysis of acid-soluble constituents in soil and aerosol was carried out with 3.5 MeV protons after the addition of internal standards, and the results obtained were compared with those obtained by using atomic absorption spectrometry (AAS).
