Sv. Fesenko et al., MATHEMATICAL-MODEL OF THE BIOLOGICAL AVAILABILITY OF CS-137 IN THE SOILS OF GRASSLAND ECOSYSTEMS, Eurasian soil science, 30(1), 1997, pp. 34-39
A mathematical model is developed describing the behavior of Cs-137 in
the soils of grassland ecosystems and its uptake by plants. The model
parameters were determined using experimental data obtained in the so
-called 50-km zone of the Chernobyl Nuclear Power Plant (ChNPP). Verif
ication of the model with independent data revealed that the changes i
n the biological availability of Cs-137 in the soil are described corr
ectly, and the model can be used to forecast the radionuclide behavior
in grassland ecosystems.
