[en] It is remarkable how much can change in a short period of time. Back in early September 2008 collective wisdom pointed to the Australian resources industry being shielded from the worst of the financial meltdown being experienced by other major economies worldwide, and all eyes were on South Australia and the Northern Territory as our uranium production centres. Fast forward six months and were are certainly feeling the pain of the global economic slowdown, and the policy banning uranium production in Western Australia (WA) has been lifted following a change of state government. Eyes are now turning west to focus on the numerous opportunities in WA.
[en] These proceedings contain the abstracts of 77 lectures. The topics focus on instrumentation, nuclear techniques and their applications for material science, surfaces, archaeometry, art, geological, environmental and biomedical studies. An outline of the Australian facilities available for research purposes is also provided. Separate abstracts were prepared for the individual papers in this volume
[en] Uranium exploration was commenced in 1973 and carried out at a regional scale over a wide area of the northern part of the Carnarvon Basin of Western Australia. As a result, pervasive uranium mineralization has been found in the Cretaceous sandstones near Manyingee Hills in the Onslow Region, which were probably deposited in a near-shore, fluvia deltaic palaeo-environment. Mineralization is generally found in poorly sorted argillaceous sandstones and siltstones near redox fronts formed by oxidizing waters circulating in reduced sediments. The principal minerals found in the two Manyingee deposits delineated so far are coffinite, uraninite with associated pyrite in the reduced zones, and phosphuranylite, siderite and limonite in the oxidized zones. The deposits are being evaluated for their amenability to in situ leaching tests
[en] In September 2009, a major dust storm crossed eastern Australia, blanketing Sydney on two occasions. We collected size-resolved aerosol samples on both days, and have subjected them to Ion Beam Analysis at ANSTO. In this paper we present these results, and compare them with some of the analysis of similar samples obtained in field trips to the Lake Eyre Basin of central Australia, the primary source region of the dust. In particular, the Fe/Al ratios (∼0.9) are similar to LEB values, and higher than northern hemisphere values (∼0.55). Salt entrainment indicates a source near dry lakes.
[en] Australia's Ambassador for Disarmament urges the Conference to establish an appropriate means for ensuring that practical work under Item 3 - the prevention of nuclear war - is carried out. The text of the Australian reply to the Secretary-General of the United Nations on the prevention of nuclear war follows the Ambassador's speech
[en] The versatility of nuclear medicine is demonstrated by the wide range of dynamic and static studies that can be performed with a single instrument to examine the heart, skeleton, whole body, lungs, thyroid brain and kidneys. A wide range of disease and organ specific radiopharmaceuticals are available
[en] Uranium is increasingly being seen by key mining professionals as a bridge to the future of both mining and power generation. Relaxed Australian Government policies have led to an increase in uranium exploration. But will further exploration lead to greater production and exports? Paul Hayes talks to Australia's leading industry professionals to find out.
