Title: Evaluation and prediction of radio-ecological situation in radiation accidents with the release of particles of irradiated nuclear fuel: the example of Chernobyl

Author: Kashparov, Valery Alexandrovich

Reference: Kiev, 1999

Keywords: radiobiology, forecasting, nuclear fuel, 90Sr

Abstract: The aim of this study was to identify and analyze the main processes of formation of radiological patterns of behavior in the environment of biologically significant radionuclides composed of fuel particles deposited after the Chernobyl accident, their parameterization based on the study of the properties of radioactive fallout and the characteristics of the environment, zoning and mapping of near-field accident zone for long-term forecasting of redistribution of radionuclides in the components of soil and vegetation cover, as well as the assessment of the radiological significance access of fuel particles into humans and farm animals.

Abstract: We compared geographically referenced ground-based measurements of gamma and beta radiation to model predictions of particle dispersion and estimate the influences of particle sizes, wind speeds, and vertical and lateral turbulence on the near-field (40 μm in diameter. These large particulates eliminate passive dispersion of oxidized nuclear fuel and aerosol releases of volatile elements as the primary sources of contamination in the Northern Plume at distances
