Distribution of137Cs in soil in Central Slovakia and fast prediction of contamination

Abstract

Radioecologically the most important radionuclide generated by the Chemobyl accident is 137Cs at present. The actual geographic distribution of the 137Cs concentrations in the soil in Central Slovalda for 1995 is presented. On the basis of measured data the relationships between 137Cs concentration in soil profiles and some local parameters (average precipitation, specific activity of 4~ soil types) was studied. Some problems in the modelling and prediction of 137Cs migration in soils are discussed too. The activity of 137Cs was measured at 45 sites. Approximately 66% of total deposition of 137Cs is in the upper 10 cm of soil.
