Application of gamma spectrometry for the characterization and influence of the archeological works of an archaeological site

Abstract The purpose of this study was the use gamma spectrometry to characterize archaeological site Molina de Aragón, located in province Guadalajara Spain. To do so, a set samples with different historical influences have been selected. were analyzed by HPGe detectors, and X-ray fluorescence, know their chemical composition. statistical activity concentration radionuclides from natural radioactive series, 40 K 137 Cs, carried out using box-and-whisker plots, cluster analysis principal component (PCA). Likewise, in-situ effective dose rates ones determined concentrations obtained evaluated verify sampling reproducibility. results made it possible classify areas Jewish Christian influence based on relationships between 232 Th 238 U series works area. least altered could also be identified Cs 210 Pb ex . Activity equivalent background Iberian Peninsula. PCA showed correlation Fe 2 O 3 , Al y ZrO thorium uranium.
