The aim of this paper is to investigate the influence of meteorology on short-term radon level of an underground laboratory. Radon concentration and ambient parameters were measured hourly at the same time between 2011 and 2013. Simultaneously, the meteorological data were obtained from the nearest weather station. Pearson's coefficients were determined among hourly radon and the rest of variables. The results show that there is a weak linear correlation among radon concentration and single variables like pressure, temperature and humidity. The same occurs with parameters formed by differences between indoor and outdoor values. For these reasons, a linear multiple regression model is used to explain variability in radon based on meteorogical parameters. Otherwise, time-series data were analyzed using the Lomb-Scargle method. Periodicities were found in the radon data which also appear in meteorogical series.Downloads
