The results of continuous automated radon monitoring, which started in 2011 with using radiometer of radon isotopes and their decay products (SARAD GmbH), are reported here. The analysis of seasonal variations of radon activity concentration in the ground atmosphere revealed maximum in spring-summer period and minimum in winter. In diurnal variations minimum appears afternoon and maximum-before noon. These results are in a good agreement with results of other radon investigations. The analysis of changes of equilibrium coefficients between radon and its decay products showed that the annual average value was 0.2 (0.25 in March-April, 0.12 in May, and 0.27 at the end of September). Significant correlations were revealed between activity concentrations of radon, thoron and some of their short lived decay products at synoptic scale. A synchronism in diurnal variations of atmospheric radon field characteristics was found only in certain time periods. Other interesting results of analysis of correlations between field characteristics of radon and produced ionizing radiation in dependence on weather conditions are also reported.
