Abstract: Radon is a naturally occurring radioactive gas, which tends to
accumulate inside built structures. It is therefore necessary to include
techniques to mitigate radon concentration during refurbishing work.
The aim of this study is to assess the effectiveness of a number of
mitigation techniques, under real conditions, to determine which is
most suitable, in each case, for use in rebuilding solutions. The
methodology consisted in performing four experimental tests on
mitigation strategies recommended by the Código Técnico de la
Edificación (Technical Building Code) (CTE-DB-HS6) and by the
Government of the Autonomous Community of Galicia, (Xunta de
Galicia, 2018). The concentration was measured with three different
systems: radon in soil at 80 cm, passive detectors to confirm mean
concentration, and continuous monitoring by devices calibrated at the
LaRUC Laboratory of the University of Cantabria, in order to compare
the results of the tests. The experiments were carried out in premises
located in a high radiation area in Arteixo (La Coruña, Spain). Four
experimental models were designed, corresponding to each of the
building solutions under study, and tested over a period of 16 days in
two repeated series of trials. The results obtained show that, of the
different strategies tested, pressurising the living space achieves an
efficient reduction of the radon concentration with a significant
simplicity of construction. This solution, compatible with the minimal
intervention and reversibility principles stablished in the charters of
Venice, Krakovia and Nara, is shown to be especially useful when
work is carried out on structures considered to be part of protected
heritage.
