Abstract
A background level of soil pollution was found of 0.2–3.5 kBq/m2 for 90Sr and 1.0–7.6 kBq /m2 for 137Cs in the Ural Region between 55° and 57° N. The average contents of 90Sr in the above-ground mass of herbaceous plants, mosses, and lichens were equivalent, while the contents of 137Cs were much higher in mosses and lichens than in herbaceous plants. The maximum range of variability of the storage capacity in relation to 90Sr was observed in herbaceous plants, while that for 137Cs was found in mosses. The content of radionuclides is determined by the species characteristics of plants within each taxonomic group.
