Abstract
A total of 18 elements (minor and trance elements) have been determined in three different samples from the bronze material of the statue Jüngling vom Magdalensberg, using instrumental neutron activation analysis. Due to the complexity of the method and the instrumentation necessary to perform irradiations and measurements this technique is rarely applied for the analysis of metal samples in archaeometry. This contribution gives a short description of the technique as well as a discussion of the results obtained with this method compared to results from other methods. Several elements, which may have diagnostic character, can be analysed very precisely with this method. Most of the elements usually determined by AAS or ICP can be determined with INAA, and sometimes it is possible to obtain better precision and accuracy with the INAA technique (e.g. for Ag, Au, As or Sb). Pb and Bi, which are of some importance in bronze analysis, cannot be analysed with conventional INAA techniques. The results for the samples from the Jüngling show a rather high Ni content which is, as discussed above, unknown from Roman bronzes. Several other trace elements, like Co or Au, have never really been explored for their usefulness in discriminant analysis, and it is suggested that these elements may be useful for bronze studies.
