GAS RADÓN. MEDIDAS DE CONCENTRACIÓN AMBIENTAL Y ACCIONES DE REMEDIO EN EDIFICIOS EXPUESTOS

Abstract

The main contribution to the radiological impact from natural radiation received by general population is due to the emission of radon (222Rn). The main objective of the project is the study of radon gas as a radioactive element in our buildings (existing and future constructions) to avoid its influence in the interior of buildings. The proposed methodology reflects on aspects of natural radioactivity in buildings, their sources, their control criteria and regulatory framework; aspects related to the presence of radon in buildings, entryways and measurement methodology of indoor environmental concentration are studied; and other protection solutions and remediation measures In both existing buildings and new construction projects are analyzed. In conclusion, the paper presents previous evaluation tools, the analysis of the existing concentration and the choice of the most appropriate mitigation / remediation measures depending on each case, through the establishment of different architectural proposals to plan actions against radon where necessary. Keywords: indoor radon; natural radiation; radon mitigation; remediation actions
