CONTENT OF COSMOGENIC ~7Be IN THE AIR LAYER AT THE GROUND AT TEMPERATE LATITUDES

摘要

The ~7Be content was measured in aerosols (once per week) and precipitation (once per month) was monitored as part of the monitoring of the radioactivity of the atmospheric layer near the ground in Rostov-on-Don in 2001-2005. Data were obtained on the correlations between the ~7Be volume activity in aerosols and the Wolf number, temperature, and amount of precipitation. The highest correlation coefficients were observed during the spring (k = 1). It was determined that the volume activity of ~7Be changes in the second half of the 23rd cycle of solar activity, i.e., the yearly average ~7Be concentration increases toward the end of the cycle. Data were obtained on the seasonal dependence of the precipitation density and the volume activity of ~7Be on the meteorological parameters (temperature, amount of precipitation).
