[1J05] Impact of a gas-to-particle conversion process on 131I atmospheric dispersion during the FDNPP accident
Keywords:Iodine-131, Gas-to-particle conversion, Numerical simulation, Fukushima Dai-ichi Nuclear Power Plant accident, GEARN-FDM
We have worked on the refinement of the migration behavior model of radioactive iodine in the environment at the time of a nuclear accident. In this presentation, using the chemical transport model GEARN-FDM, which can consider the temporal change of the properties of iodine in the atmosphere, we report the impacts of the gas-particle conversion process on the distribution of iodine-131 in the environment during the 1F accident.
