Improvement of the Ca determination accuracy with k (0)-INAA using an HPGe coaxial detector with extended energy range efficiency calibration
Original language description
We show that use of the radionuclide Co-56 for calibration of the full energy peak efficiency, epsilon, of a coaxial HPGe detector, in addition to the commonly employed set of activity standards (Ba-133, Am-241, Eu-152, Co-57, Cs-137, Y-88, Zn-65), affects significantly the epsilon values in the high energy region. This change resulted in substantial improvement of the accuracy of Ca determination by k (0)-INAA via the Ca-49 radionuclide, which emits predominantly the 3084 keV photons, as demonstrated by Ca results in NIST SRMs 1547 Peach Leaves, 1633b constituent elements in coal fly ash, and 2711 Montana II Soil.
