The airborne radioactivity and electrical properties of ground level air

The data presented in this work are the result of systematic measurements of radionuclide concentrations in air, collected with an ASS-500 high volume air sampler of the ground air monitoring network supervised by the Central Laboratory of Radiological Protection. Sampling has been done since March 1991. Simultaneously, the routine complex meteorological observations were performed. In particular, the electrical properties of ground level atmospheric air were studied with measurements of electrical field intensity, positive and negative conductivity of air and density of vertical current. The airborne 7Be concentration changes similarly to the electrical conductivity of air, while other isotopes, antropogenic or originating from the ground are correlated with dust and other meteorological factors like watering and wind.
