During several hours of the calm meteorological situation, a relatively significant level of radioactivity can be accumulated around the source. At the second stage, the calm situation is assumed to terminate and convective movement of the air induce

This article focuses on the formation of complex trajectories of radiological background fields for atypical accidental discharges of radioactivity into the atmosphere during very low wind speed episodes (calms). Within several hours of a calm meteor

The initial intention of this essay was to compare our environmental code PRIMO with the commonly accepted code COSYMA. All basic output radiological variables are in very good agreement after our careful mutual tuning of all input parameters of both

This article focuses on derivation of an effective algorithm for the fast estimation of cloudshine doses/dose rates induced by a large mixture of radionuclides discharged into the atmosphere. A certain special modification of the classical Gaussian p

The task of decision support in the case of a radiation accident is to provide up-to-date information on the radiation situation, prognosis of its future evolution and possible consequences. The reliability of predictions can be significantly improve

A stepwise sequential assimilation algorithm is proposed based on an optimisation approach for recursive parameter estimation and tracking of radioactive plume propagation in the early stage of a radiation accident. Predictions of the radiological si

The paper presents a scheme for estimation of spatio-temporal evolution of groundshine dose from radionuclides deposited on terrain in long-time horizon. Groundshine dose mitigation is modeled via semi-empirical formulas taking into account environme
