Abstract: Dispersion of radioactive material released to the atmosphere from the Fukushima Daiichi Nuclear Power Plant accident in Japan was modelled to assist the French Government in effectively providing public health advice to its citizens in Japan. It required estimation of radiation doses based on realistic scenarios and atmospheric dispersion modelling. In this paper, sensitivity studies are conducted to measure the influence of several parameters on the predicted contaminated zone. Priority is given to ground deposition of caesium 137 since it contributes the most to the long-term effects.

Keywords: atmospheric dispersion modelling; Fukushima; long-range transport models; sensitivity analysis; deposition; caesium 137; environmental pollution; Japan; air pollution; air quality; nuclear accidents; nuclear energy; nuclear power; radioactive material; public health advice; dose estimation; radiation dosage.
