Researches were carried out on a wide range of landscape conditions, at various levels of ^1^3^7Cs contamination (from 20 up to 5000kBqm^-^2), with different types of soils (approx. 20 soil varieties), which differ in texture, granulometric composition, degrees of gleyization and water regime, and anthropogenic transformation. The results showed that transfer factor (TF) values of ^1^3^7Cs differ 50 times for the natural grassy coenoses and 8 times for the semi-natural ones. The lowest ^1^3^7Cs TF values were measured in the herbages of dry meadows at automorphous loamy soils, while the highest were observed in wetland meadows at organic soils. Finally, the correlation between ^1^3^7Cs TF values and granulometric composition of soil was determined for both automorphic and hydromorphic mineral soils. ils. |
