Sažetak
TESATEX was developed to evaluate the source term generated by an open-air explosion with or without obstacles. It
lies on deeply modified SARRIM and HOTSPOT models. TESATEX can take account of the wind field influenced by buildings. It
was operated with Micro-SPRAY but could be run with any other dispersion model. Experimental validation of TESATEX and
Micro-SPRAY was successfully carried out using ‘Double Tracks’ in-field test measurements. Applications of TESATEX – Micro-
SWIFT-SPRAY modelling system are shown in the paper. Explosions of Radiological Dispersal Devices (RDD) or ‘dirty bombs’
have been simulated in Oklahoma City (downtown) and Paris (Concorde square district). The radiological pollutants dispersion is
strongly influenced by the streets network and the initial cloud configuration. Dispersion results have been post-processed to assess
the radiological impact of the considered hypothetical events.
