Investigation of depleted uranium contamination in south west of Iraq
ABSTRACT Background : The application of DU emanation for first time contaminated certain areas in the south west region of Iraq after the second Gulf war (1991). These contaminated areas were discovered in 1994. Radioactive contamination was detected using the nuclear enterprise PCM5/1 in soil samples collected from two regions near by grazing lands. This study was done for assessment of D...
متن کاملGeology and Mineralogy of Uranium Deposits from Mount Isa, Australia: Implications for Albitite Uranium Deposit Models
New geological, bulk chemical and mineralogical (QEMSCAN and FEG-EPMA) data are presented for albitite-type uranium deposits of the Mount Isa region of Queensland, Australia. Early albitisation of interbedded metabasalt and metasiltstone predated intense deformation along D2 high strain (mylonite) zones. The early sodic alteration paragenetic stage includes albite, riebeckite, aegirine, apatite...
متن کاملEvolution of uranium and thorium minerals
The origins and near-surface distributions of the ~250 known uranium and/or thorium minerals elucidate principles of mineral evolution. This history can be divided into four phases. The first, from ~4.5 to 3.5 Ga, involved successive concentrations of uranium and thorium from their initial uniform trace distribution into magmatic-related fluids from which the first U4+ and Th4+ minerals, uranin...
متن کاملDepleted Uranium in the food chain at south of Iraq
Background: Depleted Uranium (DU) is uranium with low content of U 235 produced as a result of uranium enrichment. DU has high density (19.05 g /cm3), which is 2.54 more than Iron, so it’s high penetrating power makes it preferable as emanations with high penetration power. It was used in second Gulf ware in 1991 for first time. The radioactivity of soil, plants, fruit, meat, milk and water i...
متن کاملUranium Mining: Australia and Globally
This Fact Sheet covers the start of the nuclear industry chain – uranium mining. It aims to present a concise overview of the nature of uranium, its mining and milling, and the numerous environmental and radiological aspects associated with this heavy industrial endeavour. It is clear that uranium is a finite resource and that the environmental costs associated with mining are significant and m...
