Mathematical modelling of dynamics of ⁹⁰Sr and ¹³⁷Cs migration in components of agrocenosises soil-plant cover at the late phase of radiation accident. II. Model verification and prediction assessments

Mathematical model for prediction of dynamics of ⁹⁰Sr and ¹³⁷Cs accumulation by perennial cereal grasses from contrasted by properties soils at the late phase of radiation accident was verified. Results of the model testing has shown the possibility of accountability of the role of processes, which predetermined the dynamics of radionuclides accumulation by plants (⁹⁰Sr and ¹³⁷Cs carry-over from root-inhabited soil layer, its immobilization and physical decay). Prediction assessments of ⁹⁰Sr and ¹³⁷Cs accumulation by perennial cereal grasses from contrasted by properties soils at the late phase of radiation accident was calculated with the use of realized in the model approaches
