This report presents the findings of the first-ever international assessment of the environmental impact of depleted uranium (DU) when used in a real conflict situation. Following the confirmation by NATO that DU had been used during the Kosovo conflict, the United Nations Environment Program organized a scientific field mission to investigate the possible environmental consequences. This report presents its findings and conclusions on the presence and extent of DU contamination at the areas studied, the corresponding risks to the environment, and possible mitigation actions.

Kosovo in the 1990s

The war in Kosovo was a turning point: NATO deployed its armed forces in war for the first time, and placed the controversial doctrine of 'humanitarian intervention' squarely in the world's eye. It was an armed intervention for the purpose of implementing Security Council resolutions-but without Security Council authorization.This report tries to answer a number of burning questions, such as why the international community was unable to act earlier and prevent the escalation of the conflict, as well as focusing on the capacity of the United Nations to act as global peacekeeper.The Commission recommends a new status for Kosovo, 'conditional independence', with the goal of lasting peace and security for Kosovo-and for the Balkan region in general. But many of the conslusions may be beneficially applied to conflicts the world-over.

First published in 2003. The NATO-led Operation Allied Force was fought in 1999 to stop Serb atrocities against ethnic Albanians in Kosovo. This war, as noted by the distinguished military historian John Keegan, "marked a real turning point . . . and proved that a war can be won by airpower alone." Colonels Haave and Haun have organized firsthand accounts of some of the people who provided that airpower-the members of the 40th Expeditionary Operations Group. Their descriptions-a new wingman's first combat sortie, a support officer's view of a fighter squadron relocation during combat, and a Sandy's leadership in finding and rescuing a downed F-117 pilot-provide the reader with a legitimate insight into an air war at the tactical level and the airpower that helped convince the Serbian president, Slobodan Milosevic, to capitulate.

Radioactive particles have been released to the environment from a number of sources, including nuclear weapon tests, nuclear accidents and discharges from nuclear installations. Particle characteristics influence the mobility, biological uptake and effects of radionuclides, hence information on these characteristics is essential for assessing environmental impact and risks. This publication presents a series of papers covering sources and source term characterisation, methodologies for characterizing particles, and the impact of particles on the behaviour of radioactive particles in the environment. Sources covered include the Chernobyl accident, nuclear weapons accidents at Thule and Palomares accident, the discharges from Dounreay and Krashnoyarsk, and depleted uranium in Kosovo and Kuwait. The overall aim is that an increased understanding of particle characteristics and behavior will help to reduce some of the uncertainties in environmental impact and risk assessment for particle contaminated areas.

This sudy is the second major contribution by UNEP to the scientific debate on the environmental risks and behaviour of DU associated with the use of depleted uranium wepons in a real combat situation.

A compilation of published scientific information, including human, animal, cellular, and theoretical studies, Depleted Uranium: Properties, Uses and Health Consequences provides the most current and comprehensive collection of information on depleted uranium health hazards. The editor and her international panel of contributors are clinical and ba

The production of nuclear materials for the national defense was an intense, nationwide effort that began with the Manhattan Project and continued throughout the Cold War. Now many of these product materials, by-products, and precursors, such as irradiated nuclear fuels and targets, have been declared as excess by the Department of Energy (DOE). Most of this excess inventory has been, or will be, turned over to DOE's Office of Environmental Management (EM), which is responsible for cleaning up the former production sites. Recognizing the scientific and technical challenges facing EM, Congress in 1995 established the EM Science Program (EMSP) to develop and fund directed, long-term research that could substantially enhance the knowledge base available for new cleanup technologies and decision making. The EMSP has previously asked the National Academies' National Research Council for advice for developing research agendas in subsurface contamination, facility deactivation and decommissioning, high-level waste, and mixed and transuranic waste. For this study the committee was tasked to provide recommendations for a research agenda to improve the scientific basis for DOE's management of its high-cost, high-volume, or high-risk excess nuclear materials and spent nuclear fuels. To address its task, the committee focused its attention on DOE's excess plutonium-239, spent nuclear fuels, cesium-137 and strontium-90 capsules, depleted uranium, and higher actinide isotopes.

Many veterans returning from the conflicts in Iraq and Afghanistan have health problems they believe are related to their exposure to the smoke from the burning of waste in open-air "burn pits" on military bases. Particular controversy surrounds the burn pit used to dispose of solid waste at Joint Base Balad in Iraq, which burned up to 200 tons of waste per day in 2007. The Department of Veterans Affairs asked the IOM to form a committee to determine the long-term health effects from exposure to these burn pits. Insufficient evidence prevented the IOM committee from developing firm conclusions. This report, therefore, recommends that, along with more efficient data-gathering methods, a study be conducted that would evaluate the health status of service members from their time of deployment over many years to determine their incidence of chronic diseases.

This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.
