The development of measurement methodologies to detect and monitor nuclear-relevant
materials remains a consistent and significant interest across the nuclear energy …

Nuclear security is one of the defining challenges of our time. Nuclear threats range from
deliberate dispersal of radioactive material to contaminate the vital infrastructure to diversion …

The temporal evolution of atoms and molecules in a laser-produced plasma was
investigated using optical emission spectroscopy for several metal targets (ie, Al, Ti, Fe, Zr …

We investigate the oxidation of uranium (U) species, the physical conditions leading to
uranium monoxide (UO) formation and the interplay between plume hydrodynamics and …

The early-time kinetic behavior of species in a plume produced from laser ablation of U 3 Si
2 in an environment containing 2% O 2 is characterized using time-resolved absorption …

In order to model the fate and transport of particles following a nuclear explosion, there must
first be an understanding of individual physical and chemical processes that affect particle …

Local conditions, such as temperature and oxygen availability, have a pronounced effect on
the formation and evolution of fallout following a nuclear explosion. While the behavior of …

The predictive models that describe the fate and transport of radioactive materials in the
atmosphere following a nuclear incident (explosion or reactor accident) assume that …

The transport of radioactive material following a nuclear event depends heavily on fallout
characteristics (eg, composition, shape, and size), which in turn are controlled by the …

Fundamental observations of particle size distributions are needed to develop models that
predict the fate and transport of radioactive materials in the atmosphere following a nuclear …
