Sensitivities for eight medium Z-elements with eleven different radionuclides using a new radiometric X-ray analysis technique

Abstract

In this work we shall discuss the preliminary results of employing eleven different radionuclides for elemental X-ray analysis using a new analytical technique. This new technique mixes the radioisotope directly with the sample and this source sample is directly placed on the detector window which is protected by a thin plastic film from contamination. An equal atomic mixture of eight elements (Ti, Mn, Zn, Br, Zr, Ag, Sn and Ag) was prepared and doped separately with the eleven different isotopes (Pm-147, S-35, Ni-63, Na-22, Co-137, Co-57, Cd-109, I-125, Am-241, Zn-65 and Fe-55). The spectrum of each is shown herein with a discussion of the background, signal to noise ratio, corrected peak intensities, etc. Finally, the possible future applications of this technique with some of the isotopes are presented.
