Abstract—It is argued that data on spatial distribution of 137Cs can be used to assess the character of agrogenic
transformation of soil cover in the areas with a high level of Chernobyl-derived radioactive contamination. The
methodology of this assessment is discussed by the example of a particular region. A combination of laboratory
and field methods makes it possible to determine both the statistically significant baseline fallout in particular
areas and the modern distribution pattern of 137Cs in agricultural soils.
