Abstract
In order to account for the variability in the wind field, Large-Eddy Simulation (LES) is used to assess the time-evolution of the near-range atmospheric dispersion of radioactive gases. To evaluate the gamma dose rates from cloud shine at ground level, it is coupled to a gamma dose rate model that is based on the point-kernel method. Using this coupled model, it is illustrated that the variability in the wind field can lead to dose estimates that are underestimated by up to a factor of four when conventional long-term measurements are used to estimate the dose from short-term exposures.
