Photon Standards for Energy and Efficiency Calibration of X-Ray Fluorescence Analyzers

  • A. Notea (a1) and Y. Segal (a1)


A set composed of barium-133 (7.8y), europium-152g (13.4y), bismuth-207 (30y) and americium-241 (458y), is recommended for energy and efficiency calibration of x-ray spectrometers. It is shown that the set offers over 30 energy lines in the range below 100 keV. The absolute efficiency calibration of Ge(Li) and Si(Li) detectors is demonstrated. The calibrated Ge(Li) was used for the measurement of fluorescence excitation yield from lead excited by various γ sources.
