Abstract

Theko-standardization method is based on analytical constants, which are γ-line related and the results are calculated from the peak areas of the γ-ray spectrum. Consequently, prerequisites of this method are the correct identification of the γ-lines and the avoidance of unresolved peak interferences. Because these problems are already solved with nuclide identification programs, a new variant of theko-method was developed, using the activities of the nuclides instead of the peak areas. We introduced isotope related factors,ki, calculated fromko-factors. The procedure is described and results are compared with those obtained by the γ-line based method.
