The conventional (stable) isotope mass spectrometry (IRMS) and the accelerator mass spectrometry (AMS) are a powerful search tool widely used in the field of sciences applied to the diagnostics of cultural heritage. For example, the measurement of the isotopic composition of elements such as Carbon, Oxygen, Nitrogen, Strontium, Sulfur, in the different archaeological materials, such as charcoal, bone, teeth, seeds, organic remains in pottery ceramics, marble, mortar, are a powerful tool to quantify small variations of fluxes of such elements and then get information on still unclear occupation sequences and "mode of life" in archaeological sites. In this paper, a review of use of stable and radioactive isotopic methodology on the cultural heritage will be presented, focusing both on methodological and applicative aspects. Furthermore, some examples of Bayesian statistic applied to the analysis of isotopic measurements will be given.
