“…The computational algorithms of large-sample NAA are capable of providing acceptable results even if an entire ceramic vase of about 375 g was analyzed [57,58]. Such algorithms were further tested by analyzing simulated Bronze-Age metallurgical slags with a mass of about 125 g and arbitrary shapes using a medical accelerator for PAA [59].…”

Sample-size reduction including homogenization is often required to obtain a test portion for element compositional analysis. Analyses of replicate test portions may provide insight into the sampling constant, and often much larger quantities are needed to limit the contribution of sampling error. In addition, it cannot be demonstrated that the finally obtained test portion is truly representative of the originally collected material. Nuclear analytical techniques such as neutron and photon activation analysis and (neutron-induced) prompt gamma activation analyses can now be used to study and overcome these analytical problems. These techniques are capable of obtaining multi-element measurements from irregularly shaped objects with masses ranging from multiple grams to multiple kilograms. Prompt gamma analysis can be combined with neutron tomography, resulting in position-sensitive information. The analysis of large samples provides unprecedented complementary opportunities for the mineral and geosciences. It enables the experimental assessment of the representativeness of test portions of the originally collected material, as well as the analysis of samples that are not allowed to be sub-sampled or dissolved, the analysis of materials that are difficult to be homogenized at large, and studies on the location of inhomogeneities. Examples of such applications of large-sample analyses are described herein.

Neutron activation analysis (NAA) is a nondestructive, multi‐element nuclear analytical technique with excellent sensitivity, great accuracy, and precision that has been extensively used in archaeological and cultural heritage studies. A concise description of the basic principles of the method and the experimental procedure involved, as well as the advantages of NAA, as compared to other established analytical techniques, is provided. Characteristic applications, innovative developments, and future perspectives of the technique are discussed, with emphasis on the fields of archaeology, provenance, authentication, and cultural heritage research. The unique capabilities and the great potential of NAA for nondestructive analysis of precious artifacts and historical materials are presented.
