Se presenta una evaluación de la exactitud del análisis por activación neutrónica según el método del k sub cero, usando zinc laminado como comparador. Se ha encontrado una buena precisión intra e inter analistas, así como un buen grado de veracidad para la mayoría de elementos. Se describe también la determinación de parámetros experimentales importantes, tales como la determinación de la eficiencia de conteo, coincidencias verdaderas γ-γ, preparación del comparador y aseguramiento / control de la calidad.

Fragments of archaeological pottery from a rescue excavation at the site of La Real in Arequipa, Peru, were studied by instrumental neutron activation analysis, k 0 method. Analytical data were processed by multivariate statistical techniques, comparing the chemical composition of the studied samples versus the information available in our database on the chemical composition of archaeological pottery from Conchopata (Ayacucho), Cotahuasi (Arequipa), Huaro (Cusco) and Tiwanaku (Bolivia). The results obtained revealed that most of the samples were likely made locally at La Real, while others correspond to the chemical composition of the different groups considered, showing evidence of the presence of foreign pottery in the site and a small group which were not classified.
