Numerous scenarios exist whereby radioactive particulates are transported
between spatially separated points of interest. An example of this phenomenon is, in the
aftermath of a Radiological Dispersal Device (RDD) detonation, the resuspension of
radioactive particulates from the resultant fallout field. Quantifying the spatial
distribution of radioactive particulates allow for the calculation of potential radiation
doses that can be incurred from exposure to such particulates. Presently, there are no
simulation techniques that link radioactive particulate transport with subsequent radiation
field determination and so this thesis develops a coupled Computational Fluid Dynamics
(CFD) and Monte Carlo (MC) Radiation Transport approach to this problem. Via
particulate injections, the CFD simulation defines the spatial distribution of radioactive
particulates and this distribution is then employed by the MC Radiation Transport
simulation to characterize the resultant radiation field. GAMBIT/FLUENT are employed
for the CFD simulations while MCNPX is used for the MC Radiation Transport
simulations. / UOIT
