Estimation of the height of the mixing layer using polonium concentrations in the atmosphere. An attempt at modelling. L.

Short-lived isotopes of polonium, lead and bismuth originate are a result of the radon decay in air. The idea of thls work is to make the model of mixing layer heights variation basing on polonium 218~o concentrations. The relation between emanation of radon from the soil surface and variation of polonium in the air and mixing layer and meteorological conditions were determined. In 2000-2002 measurements of radon and polonium concentrations
