Neutron diffraction techniques are applied to the study of burned human skeletal remains, for assessing heat-induced changes associated to alterations in bone´s microcrystallinity. The results, coupled to vibrational spectroscopy data (INS, Raman, FTIR), are expected to provide an improved understanding of the structural changes undergone by bone upon burning. A quantitative relationship between spectroscopic and diffraction parameters, dimensional variations and specific burning conditions is sought, with a view to relate burned to pre-burned parameters. This is an innovative way of tackling heat-induced changes in human bone, with a high impact in forensic investigation. This work follows successful experiments on MAPS and TOSCA, which were the first studies on human burned bones by neutron techniques and allowed us to identify spectral biomarkers of heat-elicited alterations [1].
