COMPARISON OF THE CATALOGS OF THE K(O) AND THE K(ZN) SINGLE COMPARATOR METHODS FOR STANDARDIZATION IN INAA

The independently measured catalogues of two single comparator methods for standardization in INAA, i.e., the k(Zn)- and the k(O)-method, we re compared. Many reactions were listed only in the k(Zn)-catalogue; i n these cases other literature data were used to supplement the k(O)-c atalogue. The agreement between the k(Zn)- and the k(O)-catalogue was found to be much better than the agreement between the k(Zn)-catalogue and other literature data. It is therefore suggested to use the conve rted k(Zn)-catalogue as a supplement of the previously published k(O)- catalogue.
