The Council Directive BSS 2013/59/Euratom establishes the Basic Safety Standards (BSS) that implies obligation to develop a regulatory framework to actively work to reduce radon exposure for workers and the public, and to reduce the reference level for the annual mean activity concentration in air to a maximum value of 300 Bq/m3 (REF). To fulfil the regulation guidelines, it is necessary to determine the critical parameters that affect to radon concentration indoor, which could allow carry out remedial actions. The study presented is performed within the framework of a national research project whose main objective is to study the validity of simulation tools for radon in air levels in closed rooms, which allow the analysis of different scenarios to develop action criteria.
One of the experimental study cases for the set up and validation of developed models is the so-called Pilot House, located in the former uranium mine managed by the Spanish Uranium Company (ENUSA), based in Saelices el Chico (Salamanca, Spain). It is a module designed which pretends to reproduce the typological characteristics of a Spanish house (continental territory) using common materials for this construction type.
In this presentation we will show the selection of parameters studied that could affect to indoor radon concentration in the Pilot House, the measurements methodology, the data collection system, and the time series obtained. It is therefore shown the time series of indoor radon concentration, radon concentration in soil, the meteorological parameters, And the differential air pressures measured at different points both inside and outside the pilot house, including those inside the soil around the building. Those time series will be the base for the radon simulation models available
