Book Description
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.

Book Description
Volume 52 of Reviews in Mineralogy and Geochemistry updates our knowledge of U-series geochemistry, offer an opportunity for non-specialists to understand its basic principles, and give us a view of the future of this active field of research. In this volume, for the first time, all the methods for determining the uranium and thorium decay chain nuclides in Earth materials are discussed. It was prepared in advance of a two-day short course (April 3-4, 2003) on U-series geochemistry, jointly sponsored by GS and MSA and presented in Paris, France prior to the joint EGS/AGU/EUG meeting in Nice.

Book Description
All the solid fuels fossil energy and mineral commodities we use come out of the Earth. Modern society is increasingly dependent on mineral and fossil energy sources. They differ in availability, cost of production, and geographical distribution. Even if solid fuels, fossil energy resources and mineral commodities are non-renewable, the extracted metals can to a large extent be recycled and used again and again. Although the stock of these secondary resources and their use increases, the world still needs and will continue to need primary mineral resources for the foreseeable future. Growing demands have begun to restrict availability of these resources. The Earth is not running out of critical mineral resources – at least for the near future – but the ability to explore and extract these resources is being restricted in many regions by competing land use, as well as political and environmental issues. Extraction of natural resources requires a clear focus on sustainable development, involving economic, environmental and socio-cultural aspects. Although we do not know what the most important resources will be in 100 years from now, we can be quite certain that society will still need energy and a wide range of raw materials. These resources will include oil and gas, coal, uranium, thorium, geothermal, metallic minerals, industrial and specialty minerals, including cement, raw materials, rare-earth elements. A global approach for assessing the magnitude and future availability of these resources is called for – an approach that, with appropriate international collaboration, was started within the triennium of the International Year of Planet Earth. Some global mineral resource assessments, involving inter-governmental collaboration, have already been initiated. The International Year of Planet Earth helped to focus attention on how the geosciences can generate prosperity locally and globally, as well as sustainability issues in both developed and developing countries.

Book Description
The explosion on 26 April 1986 at the Chernobyl nuclear power plant and the consequent reactor fire resulted in an unprecedented release of radioactive material from a nuclear reactor and adverse consequences for the public and the environment. Although the accident occurred nearly two decades ago, controversy still surrounds the real impact of the disaster. Therefore the IAEA, in cooperation with other UN bodies, the World Bank, as well as the competent authorities of Belarus, the Russian Federation and Ukraine, established the Chernobyl Forum in 2003. The mission of the Forum was to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. This report presents the findings and recommendations of the Chernobyl Forum concerning the environmental effects of the Chernobyl accident.

Book Description
The primary objective of this study is to contribute to a better understanding of the interaction of depleted uranium as a source of low dose radiation with the living world and humans in a contaminated environment. There has been increased interest in biological effects of low dose radiation after the incident in Chernobyl. Uncertainty of epidemiological studies about the health effects of low-dose radiation arises from the fact that the biological effects of low-dose radiation do not relate obligatory to DNA damage. Military use of depleted uranium (DU) for decades put the problem of low-dose radiation exposure in the spotlight. The explanation related to the limited effects of Ñ-emitting nuclear weapons, including DU, was based to some extent on the fact that alpha particles have a short track in air. This paradigm has changed with the realisation that nano- and micro-sized particles of DU could have a global atmospheric movement. The idea about the spreading of uranium particles through air masses across the globe arose from the results of air pollution measurement. Due to uncontrolled military use of high amounts (a thousand tons) of depleted uranium, numerous unusual environmental physical manifestations were recorded in the last two or three decades. Simultaneous monitoring of natural phenomena on Earth and in the atmosphere has revealed an exceptional parallelism between the phenomena in the environment and in the living world. Our knowledge has evolved from in-vitro studies of radiation exposure to a more comprehensive understanding of unexpected and poorly understood natural phenomena, whose consequences may be achievable according to the theory of litosphere-atomsphere-ionospehere and biosphere coupling. The emission of radiation in the course of several decades due to corrosion of scattered remnants of DU armaments, which has been intensified by the repeated bombing of the regions within the range of the transfer of radioactive particles through the air, strikes a broad territory and numerous populations, and unavoidably leads to in-vivo Petkau effect. The Petkau effect is a challenge for science to declare the future health strategy with the main goal focused on minimising the early as well as delayed in-vivo effects of depleted uranium. As inhaled air is the main source of internal contamination, further research on this topic is valuable, especially in terms of overcoming inter-individual variability. The authors propose a simple model based on apoptotic parameters and artificial network method for individualised estimation of tissue response to low-dose tobacco exposure. Non-targeted effects of radiation are time-evolving and can lead to delayed health effects, including cancerogenesis. The authors discuss the importance of an individual approach to the diagnosis and selection of appropriate therapy, based not only on the results of the expression analysis, but also on metabolic and apoptotic tissue properties. Humanity is the main subject of the authors' study. Understanding the basic principles of cell biology and radiation interaction with living matter is supported by authentic medical data obtained from patients originating from the territories which were geographically close to each other (Serbia and Montenegro seaside, as well as Bosnia and Herzegovina, the territories of the former Yugoslavia).
