Study, measurement and mitigation of radon activity concentration in the School of Computer Science of A Coru ña in the North West of Spain

A study of the radon activity concentration was carried out at the School of Computer Science of
‘Universidade da Coruña’ (UDC, Spain). For this purpose, building location, the type of soil and the
construction materials were analysed. Subsequently, the radon activity concentration was determined
using two different techniques: measurement in situ with an on-site ionization chamber detector
(short term) and measurement with trace detectors (long term). Based on the results obtained, and
according with the Spanish Law (Spanish Official Bulletin —Boletín Oficial del Estado, of 21 December
2011, IS-33 Instruction), corrective works were performed, consisting on the installation of a
forced ventilation system underneath the extent of the suspended floor in order to mitigate the high
radon specific activity in the building. Four months and 3 years after the works, new measurements
were carried out in order to verify the effectiveness of the new ventilation system, obtaining a
decrease...
