Abstract

Atmospheric transport and dispersion modelling can provide crucial information to evaluate the impact of regular or accidental releases of radionuclides. One of the processes that depletes radionuclides from the atmosphere is deposition, which causes ground contamination thereby potentially impacting the food chain. Wet deposition in particular plays an often dominant role in the total deposition of radioactive material following a release of radioactive particulates in the atmosphere. In this work, the sensitivities of wet deposition contributions will be quantified with atmospheric dispersion model FLEXPART. The transport and deposition of Cs -137 as a result of the Fukushima Daiichi Nuclear power plant accident is used as a test case for this sensitivity study. A novel method is developed which extracts the individual scavenging contributions from the FLEXPART simulations and optimises them by comparing to measurements.
