Some irregularities observed in the analysis results of k0-NAA

Abstract

Since 1996, two new cases were detected in our laboratory for which the elemental concentrations derived from k 0 neutron activation analysis seem questionable. These cases concern the inconsistencies observed (1) in the concentration of Ca obtained via 47Ca and 47Sc, and (2) in the concentration of Yb obtained via the 228.5 and 396.3 keV lines of 175Yb. A recommendation is made to re-evaluate the corresponding k 0-values or true-coincidence correction factors.
