Abstract

Estimation of the height of the mixing layer using polonium concentrations in the atmosphere. An attempt at modelling. L. Osrodkal, E. ~rajny', M. ~ o j t ~ l a k z , K. skubacz3 & J. skowronek3 '~nstitute of Meteorology and Water Management, Branch of Katowice, Poland 2 Silesian University, Institute of Mathematics, Poland 3~entral Mining Institute, Laboratory of Radiometry, Poland Abstract The measurement of the radon 2 2 2 ~ concentrations and its short-lived daughter is one possibility to obtain information on the dynamics of the lower boundary layer. 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
