Singularidades en el diseño de soluciones de protección frente a gas radón

Abstract

[ES]: El isótopo del radón Rn-222, aparece en la naturaleza como producto de la desintegración natural del radio-226, común en la corteza terrestre. El potencial de exhalación de un terreno viene definido, por un lado, por el contenido de radio del sustrato (por ejemplo, los graníticos), y por otro, por la permeabilidad del mismo que permite la movilidad a través de los poros (fracturados). El radón, como elemento gaseoso, posee una alta movilidad y puede penetrar en los edificios a través de fisuras o grietas por advección o por difusión a través de la propia permeabilidad de los materiales de la envolvente que estén en contacto con el terreno. La acumulación de este gas en los recintos cerrados puede elevar las concentraciones y constituir un riesgo para la salud de las personas que lo inhalen. La OMS advierte de sus efectos, situándolo como agente cancerígeno de grado uno, siendo la segunda causa de contracción de cáncer de pulmón (la primera sería el tabaco). En esta comunicación se ofrecen pautas de diseño, y las particularidades asociadas a las estrategias de actuación, basándose en los estudios llevados a cabo a través de proyectos de investigación.

[EN]: The isotope of radon Rn-222, appears in nature as a product of the natural disintegration of radio-226, common in the earth's crust. The exhalation potential of a terrain is defined, on the one hand, by the radio content of the substrate (for example granitic), and on the other, by the permeability of the same that allows mobility through the pores (fractured). Radon, as a gaseous element, has a high mobility and can penetrate buildings through fissures or cracks by advection or diffusion through the permeability of the materials of the envelope that are in contact with the ground. The accumulation of this gas in enclosed areas can increase concentrations and constitute a risk to the health of people who inhale it. The WHO warns of its effects, placing it as a carcinogen of grade one, being the second cause of lung cancer contraction (the first would be tobacco). This communication offers design guidelines, and the particularities associated with the strategies of action, based on the studies carried out through research projects.

Este trabajo se ha podido desarrollar gracias a los proyectos de investigación RADÓN CERO (Nº Ref. BIA2014-58887-R) y PERFORA (RTC2015-34-64-5), ambos financiados por el Ministerio de Economía y Competitividad, del Gobierno de España.
