Summary

At operation of perennial monitoring of Ukrainian 90Sr contaminated after Chernobyl accident agricultural holding was taken 510 conjugate couple of nuclide concentration values in system "soil to plant", which characterized of radionuclide accumulation by 5 agricultural crops on 3 prevalent soil types. The existence of linear dependency between radiostrontium specific activity in plants and soil density contamination by Chernobyl fallout was confirmed. It is determined what transfer factor TF 90Sr from soil in agricultural crops decrease with time after fallout. The model of TF 90Sr dynamic was developed and its parameters for basic agricultural crops and Ukrainian soil were estimated qualitative. This admitted to predict the agricultural crops contamination after radioactive fallout.
