Abstract In order to model the fate and transport of particles following a nuclear explosion, there must first be an understanding individual physical chemical processes that affect particle formation. One interaction pertinent fireball chemistry resultant debris formation is between uranium oxygen. this study, we use laser ablation metal in different concentrations oxygen gas, either 16 O 2 or 18 , determine influence on rapidly cooling uranium. Analysis recovered particulates using...
Microscopic fuel fragments, so-called "hot particles", were released during the 1986 accident at Chornobyl nuclear powerplant and continue to contaminate exclusion zone in northern Ukraine. Isotopic analysis can provide vital information about sample origin, history contamination of environment, though it has been underutilized due destructive nature most mass spectrometric techniques, inability remove isobaric interference. Recent developments have diversified range elements that be...
