Radon concentrations in cave houses of Crevillente. A study about typological factors and proposals for remedial actions based on ventilation techniques

[EN]: The present paper analyses the influence of typological factors on radon gas concentration in the cave houses of Crevillente (Alicante province, Spain). Despite their location in an area included in the lowest category of potential exposure to radon (according to the Marna Project), a radon ac...

Despite their location in an area included in the lowest category of potential exposure to radon (according to the Marna Project), a radon accumulation exceeding the recommended values is obtained; room depth emerges as a parameter which increases the concentration found; small differences are also detected between interior and exterior temperatures (3°C), thus moving away from the usual comfort parameters and making it necessary to use additional air-conditioning systems so that these rooms can be habitable. Furthermore, the study of infiltrations reveals that the number of renovations/hour needed to reduce the existing radon concentration to 300 Bq/m3 is feasible even starting from very high initial conditions; however, the most restrictive recommendations (100 Bq/m3 ) are unlikely to be reached, since they imply over 13 renovations/hour of the whole dwelling volume even starting from relatively low concentrations.[ES]: El presente trabajo analiza la influencia de factores tipológicos en la concentración de gas radón existente en las casas cueva de Crevillente (provincia de Alicante, España). A pesar de la ubicación de estas viviendas, en un área incluida en la categoría más baja de exposición potencial al radón (de acuerdo con el Proyecto Marna), se obtiene una acumulación de radón que sobrepasa los valores recomendados; la profundidad de la estancia se identifica como un parámetro que incrementa la concentración obtenida; también se detectan diferencias bajas entre temperaturas interiores/exteriores (3°C), alejándose así de los parámetros habituales de confort y haciendo imprescindible el uso de climatización añadida para acondicionar estas estancias. Además, el estudio de infiltraciones constata que el número de renovaciones/hora necesario para reducir a 300 Bq/m3 la concentración de radón existente es asumible incluso partiendo desde condiciones iniciales muy elevadas; sin embargo, las recomendaciones más restrictivas (100 Bq/m3 ) son poco viables de alcanzarse ya que suponen más de 13 renovaciones/hora del volumen total de la vivienda, incluso partiendo de concentraciones relativamente bajas.The present paper was drawn up under the auspices of a Grant for Stays of Research Staff with a PhD in research centres located outside the Valencian Autonomous Region awarded to its first author (reference BEST/2015/251) at Departamento de Construcción in the Instituto Ciencias de la Construcción Eduardo Torroja (Madrid, Spain).Peer reviewedPontificia Universidad Católica de ChileGeneralitat ValencianaConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202020202018info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/211639reponame:DIGITAL.CSIC.
