“…In forest, the intercepted radioactive dust was relocated to the forest floor by the processes of leaf fall or by rain leaching the material from the canopy (throughfall). Migration of radionuclides in soil depends on numerous and various parameters, among others, on soil type, physicochemical properties of soil horizons or chemical properties of soil solution (Odintsov et al 2005). The distribution of deposited element in soil in a given area is influenced by amount of initial fallout, its physicochemical properties as well as horizontal and vertical migration rate in soil.…”

Distribution of 137 Cs and 239,240 Pu in the forest soils horizons of the Opole Anomaly was established. Gamma and alpha spectrometry was used for determination of these isotopes. It was found that the 137 Cs activity was approx. 1,000 times higher than that of 239,240 Pu. The highest activities of both radioisotopes were found close to the boundary region in soil profile where the organic horizon turns into the inorganic one. Cluster analysis did not clearly indicate the group's existence in data in respect to 137 Cs and 239,240 Pu activities and organic matter content. Distributions of 137 Cs and 239,240 Pu in soil horizons were non-normal but similar to each other. These distributions were substantially different from that one for organic matter content. The data were separated into two groups, for organic and inorganic soil horizons, respectively. Data transformation using Box-Cox formula was performed following by standardization.Mutual relationships between variables were investigated using ordinary and robust regression methods. Good correlation between 137 Cs and 239,240 Pu was found. No significant relationship between organic matter content and radioisotopes activity was asserted.
