ВАРИАЦИИ СОДЕРЖАНИЯ РАДОНА В ПОЧВЕ И МЕТЕОРОЛОГИЧЕСКИХ ПАРАМЕТРОВ В ОБСЕРВАТОРИИ ЯНГИБАЗАР В 2022–2025 ГОДАХ

This paper presents the results of continuous observations of soil radoncontent, air humidity, and atmospheric pressure at the Yangibazar Observatory during2022–2025. The main objective of the study is to identify the temporal patterns of radonvariability and to assess the relationship between the observed variations and seasonaland geodynamic processes. Radon flux density was measured using an RR-3s radonmonitor installed in a borehole approximately 1 m deep. Analysis of daily, monthly, andannual values revealed a stable seasonal pattern in soil radon variability. During 2022–2024, the maximum radon flux density values reached 15.8–17.4 Bq/m²·s, whereas themaximum value in 2025 was 14.3 Bq/m²·s. No sharp and prolonged changes in radoncontent were identified during the observation period. The observed variations werepredominantly seasonal, indicating the importance of considering meteorological factors,particularly air humidity and atmospheric pressure, when interpreting radon variations.The obtained results demonstrate the need for an integrated analysis of radon monitoringdata together with meteorological and geodynamic parameters in studies of seismicprocesses.
