Abstract
Understanding mechanical resuspension of particles in the size range of 0.1 to 15µm is necessary to build accurate plume and dosimetry models for emergency phase response after any nuclear event. Particles in this size range are resuspended solely by mechanical disturbance as opposed to wind disturbance. After a nuclear event, such as an improvised nuclear blast or a nuclear power plant meltdown, radioactive particles can adhere to road dust particles in the sizes of 0.1 to 15µm. Past experiments and current models are not designed to accurately predict how to track these plume dispersions due to a lack of phenomenological understanding and experimental data. Experimental field data can be very difficult and time consuming to obtain due to the lack of accurate guidance in performing these tests and difficulty identifying equipment that can handle the strains of performing these tests. In this vein, this report aims to describe the limitations in obtaining field data and the history of mathematical modeling of particle resuspension. As a part of this dissertation, this thesis will investigate current equipment, create custom devices, and test those devices in field studies. Lastly, I will use these devices to take part in developing and testing stabilizers to reduce resuspension.
