The work deals stochastic cosimulation of ⁹⁰Sr and ¹³⁷Cs soil contamination after the Chernobyl fallout. Cosimulation is to model spatial variability and uncertainty of the spatial distribution. Cosimulation results are significantly improved by additional data on the secondary variable ⁹⁰Sr, which has more measurements than ⁹⁰Sr. Cosimulations are compared with sequential Gaussian simulations of single ⁹⁰Sr. All the modelling is applied to real data on the Chernoby fallout.
