Abstract

Several experiments of dispersion of radioactive particulate matter after an explosion have been performed by the National Radiation Protection Institute of the Czech Republic. These experiments were set up to simulate an attack by a so-called “dirty bomb”. Many pieces of experimental equipment were used to measure aerosol concentration, deposited activity, dose rates and basic meteorological parameters. In this contribution we perform a computer simulation of this experiment using our in-house CFD (LES) code. We mainly concentrate on deposition of activity in the area of interest and the time evolution of concentration. These experiments are also used as a model short scale scenario for Working group 9 of project EMRAS II coordinated by the IAEA.
