Estudio, medida y mitigación de la concentración de radón en la Escuela Universitaria de Arquitectura Técnica de la Universidade da Coruña

A study of radon concentration has been carried out at the University of A Coruna’s Technical Architecture School. For that purpose, soil and construction materials, as well as building location have been analyzed. After that, measurements have been performed in order to find out radon concentrations. Two techniques have been used to make that enquiry for both short term and long term measurements: for short term, measurements were made using an on-site ionization chamber detector, while, for long term, trace detectors have been employed. Due to the results, and according with the Spanish Law (Spanish Official Bulletin – Boletin Oficial del Estado, of December 21, 2011, IS-33 Instruction), corrective works have taken place (cracks sealing, installation of a forced ventilation system) in order to diminish the high radon concentrations. After works, new measurements proved that radon concentration values lowered about 50 % and 90 %.
