Keywords: radon anomaly, radon volumetric activity, fault, meteorological parameters, Archean-Lower Proterozoic basement.
Аnnotation: In the process of studying the fault tectonics of the Vychegodskiy trough, an area of high concentrations of soil radon was identified, confined to the zone of the Vychegodsko-Lokchimkiy fault. To localize the radon anomaly, measurements of the volumetric activity of radon were carried out over a network of observation points. Air sampling at each point was performed from the wellhead with a depth of 0.5 m and a diameter of 0.1 m. Based on the data obtained, an intense radon anomaly was contoured. At different times, the size, shape and intensity of the anomaly changed, but its center always remained in the same place. According to areal observations, in the central part of the anomaly, the size of which was 2×2 km, the radon concentration reached 3800–4800 Bq/m3. The results of continuous daily monitoring in the center showed that the concentration of radon is subjected
to daily dynamics, which directly depends on meteorological parameters, namely on temperature and humidity. At night, with a decrease in temperature and an increase in air humidity, the level of radon increased to an average of 6000–8000 Bq/m3, in rare cases – up to 10000–12000 Bq/m3. In the daytime, with an increase in temperature, a decrease in the volumetric activity of radon was noted. In addition to the daily dynamics, seasonal variability of the radon field was observed. In autumn, radon levels are lower than in summer, which is associated with short-term precipitation and, as a result, the filling of the pore space with water. The Archean-Early Proterozoic basement composed of gneisses, amphibolites, quartzites, and migmatites and occurring at a depth of 2 km is considered as the main source of radon. Due to the fact that the anomaly is located in the zone of influence of the Vychegodsko-Lokchimsky fault, the latter is considered the main way of transporting fluids to the surface.
