Arqueometria e o estudo das ânforas lusitanas do Núcleo Arqueológico da Rua dos...
Dias, M. I.; Trindade, M. J.; Fabião, C.; Sabrosa, A.; Bugalhão, J.; Raposo, J.; Guerra, A.; Duarte, A. L.; Prudêncio, M. I.The archaeological investigation of the area today integrated in the Núcleo Arqueológico da Rua dos Correeiros (NARC, CNS 1950) allowed the collection of a considerable number of Lusitanian amphorae. The archaeometric study of some of these amphorae, through chemical analysis of ceramic body by neutron activation, and comparison with similar existing compositional studies for three production centers of the Tag...
Perfis de contaminação e inactivação microbiana em azulejos
Silva, T.; Cabo Verde, S.; Cardoso, G.; Fernandes, A. C.; Trindade, M. J.; Burbidge, C. I.; Dias, M. I.; Botelho, M. L.; Prudêncio, M. I.One of the major challenges in the conservation of cultural heritage is the prevention and control of contamination caused by microorganisms. The goals of the present study were the evaluation of methodologies for the characterization and quantification of the bioburden present in ancient ceramic tiles, and the estimation of the minimum dose of gamma radiation (Cobalt-60) necessary to inactivate the bioburden o...

Pereira, M. A. Stanojev; Prudêncio, M. I.; Marques, J. G.; Figueiredo, M. O.; Dias, M. I.; Silva, T. P.; Esteves, L.; Burbidge, C. I.; Trindade, M. J.Neutron tomography (NT) setup installed at the Portuguese Nuclear Research Reactor (Sacavém, Portugal) has been applied to visualize the inner structure of ancient Portuguese glazed tiles undergoing conservation treatments. Neutrons have the advantage of interacting strongly with hydrogen, so NT is able to map hydrogenous compounds with high sensitivity. NT showed that brushing technique appears to be more effi...

Chemical tracers of Lusitanian amphorae kilns from the Tagus estuary (Portugal)
Dias, M. I.; Prudêncio, M. I.; Gouveia, M. A.; Trindade, M. J.; Marques, R.; Franco, D.; Raposo, J.; Fabião, Carlos; Guerra, AmílcarIn this paper, the characterization of Roman amphorae from the Porto dos Cacos (PC) and Quinta do Rouxinol (QR) workshops, in the Tagus estuary, dating to a period between the 1st and 5th century AD was carried out on the basis of instrumental neutron activation analysis data on 260 amphorae fragments, together with mineralogical compositional studies obtained by X-ray diffraction. Special attention was devoted...
