ROLE OF SOIL AND CLIMATE CHARACTERISTICS IN THE FORMATION OF RADIOACTIVE CONTAMINATION OF MUSHROOMS

Abstract

The present work is devoted to an analysis of the regularities of 137Cs accumulation by forest mushrooms after the Chernobyl accident and the role of physical-chemical soil characteristics and climate characteristics in the formation of radioactive contamination of mushrooms of different biological types. For the analysis of obtained results, database, containing the values of about 500 measurements of 137Cs concentration in mushroom samples was used. Aggregated transfer factor (Tag) was used as a parameter of radionuclide migration from soil to mushroom.Quantitative relationship between 137Cs Tag from soil to different species of mushrooms and soil properties was obtained as regression equations with respect to the most closely correlated parameters.
