Statistical Analysis of Monitoring the Results of the Radon Level and Meteorological Parameters in the Buildings of Geophysical Stations in Azerbaijan

Resumo

In this paper, we present a statistical analysis of the results of monitoring the radon content and meteorological parameters (atmospheric pressure, temperature, and humidity) in the buildings of three stationary geophysical stations in Azerbaijan (Sheki, Shamakhi, and Kurdemir) from April 1, 2016 to September 30, 2017 and the level of their interrelation. The studied database included 13 152 measurement complexes with an hourly interval. Short-term (intraday) and medium-term (intra-annual) changes in the parameters and the correlation dependence between them are considered. Radon fluctuations at various stations are generally ambiguous due to the different geological conditions at their location and the building construction. The statistical analysis of the data for the entire observation period showed a weak correlation between the radon content and climatic parameters. However, according to the monthly average values for 2017, there is a positive correlation between changes in the radon levels and the humidity in the air at all three stations during the year while, a decrease in atmospheric pressure and an increase in air temperature are accompanied by an increase in the radon concentration in the buildings of the Shamakhi and Sheki stations.
