Transfer of cesium-137 from forest soil to moss Pleurozium schreberi
Original language description
Moss (Pleurozium schreberi) and soil samples collected in 2009 in Bory Stobrawskie forest were used to study the transfer factor (TFCs) and aggregated transfer factor (Tag) of radiocesium from forest soil to moss. This investigation also included determination of 40K activity, pH, conductivity and organic matter content in soil. The mean 137Cs activities were 179 Bq/kg d.m. in soil samples and 203 Bq/kg d.m. in moss. The TFCs of 137Cs from soil to moss was varied in the range from 0.1 to 3.3. The mean surface activity was 11.2 kBq/m2. The Tag values were limited in the range from 0.001 to 0.058. Additionally the TFK values for 40K were computed. It was found that the main contribution of 137Cs activity in environment originates from soil and activitiesof 137Cs and 40K were usually higher in moss than in soil. It can be supposed that the 137Cs isotope migrates to moss from its surrounding. Among others, statistically significant correlation between TF of 137Cs and activity of 40K in so
