Advances in Materials Science and Engineering Assessment of Gamma Radiation Hazards Related to Geologic Materials: Comparison of Results by Field Gamma Spectrometry and Laboratory Methods
Sanjurjo-Sánchez, Jorge; Couto, Miguel; Alves, Carlos (Wiley, 2018)[Abstract] Geologic materials are a potential source of external gamma radiation in buildings due to the presence of radioisotopes (40K and isotopes from U and Th decay families). The contents of these radioisotopes can ... -
Aeolization on the Atlantic Coast of Galicia (NW Spain) From the End of the Last Glacial Period to the Present Day: Chronology, Origin and Evolution of Coastal Dunes Linked to Sea-Level Oscillations
Arce-Chamorro, Carlos; Vidal Romaní, Juan Ramón; Grandal-d'Anglade, Aurora; Sanjurjo-Sánchez, Jorge (Wiley, 2022-10-05)[Abstract] The Atlantic coast of Galicia (NW Spain) is a high-energy environment where shingle beaches are currently developing. These coarser sediments alternate with sandy deposits which are also considered as beaches ... -

Assessment by portable gamma spectrometry of external gamma radiation hazard due to granitic materials and indoor space typology
Lima, Marco; Sanjurjo-Sánchez, Jorge; Alves, Carlos (Multidisciplinary Dixital Publishing Institute, 2017-12-14)[Abstract] Building materials can contribute to ionizing radiation hazards due to their variable content in radioactive isotopes. Uranium, thorium, and potassium radioisotopes are present in various building materials due ... -
Bacteria, guano and soot: source assessment of organic matter preserved in black laminae in stalagmites from caves of the Sierra de Atapuerca (N Spain)
Kaal, Joeri; Martínez-Pillado, Virginia; Martínez Cortizas, Antonio; Sanjurjo-Sánchez, Jorge; Aranburu, Arantza; Arsuaga, Juan Luis; Iriarte, Eneko (Union Internationale de Spéléologie, 2021-04-14)[Abstract] Speleothems are a recognized source of paleoclimatic information, but their value as a source of signals from human activities in caves with an archaeological record has rarely been explored. Previous studies ... -
Biomineral deposits and coatings on stone monuments as biodeterioration fingerprints
Sanjurjo-Sánchez, Jorge; Alves, Carlos; Freire, David M. (Elsevier, 2024)[Abstract] Biominerals deposition processes, also called biomineralisation, are intimately related to biodeterioration on stone surfaces. They include complex processes not always completely well understood. The study of ... -
Chronology of Coastal Alluvial Deposits in The Ria de Coruña (NW Spain) Linked to the Upper Pleistocene Sea Level Regression
Arce-Chamorro, Carlos; Sanjurjo-Sánchez, Jorge; Vidal Romaní, Juan Ramón (MDPI, 2022-10-04)[Abstract] The Ria de Coruña (NW Spain) is a wide estuary recently formed by the flooding of the Mero fluvial valley lowlands during the last postglacial transgression. During the last glacial episode, with the sea level ... -
Chronology of Four Climbing Dune Outcrops on the Atlantic Coast of Galicia (NW Spain) Linked to the Sea Level Fall during the MIS6 and MIS4 Isotopic Stages
Arce-Chamorro, Carlos; Vidal Romaní, Juan Ramón; Sanjurjo-Sánchez, Jorge (MDPI, 2022-02-23)[Abstract] Numerous sandy deposits, interpreted as the remains of old climbing dunes, are preserved on the cliffy coast of Galicia (northwest Spain). These deposits can be found both in open coastal areas and in the interior ... -
