In its present condition, the dam of the tailings pond is less stable than is recommended by international practice. A surveillance system has been established to observe both vertical and horizontal soil movement and the buildup of stresses in the soil. The stability of the dam depends primarily on erosion by shore processes and the consequent reduction of the counterbalance, as well as the reduction in strength of the Cambrian clay underlying the dam caused by creep and by water percolating to the bottom of the pond. The most critical need is to enlarge the counterbalance and to stop...

In the summer of 1997 some twelve lecturers and sixty students met for ten days in Budapest Hungary in a NATO Advanced Studies Institute (ASI) to consider "New Scientific and Technical Aspects of Verification of the Biological and Toxin Weapons Convention." In many ways the meeting was ahead of its time. The Ad Hoc Group was only then about to move to the discussion of a rolling text of the Protocol to the Biological and Toxin Weapons Convention (BTWC). It had been mandated to negotiate the Protocol by the Special Conference which had considered the work of the VEREX process that had taken...

The Editors would like to thank the authors of the papers at the Advanced Research Workshops for their excellent presentations at the workshops and the production of their drafts. We are indebted to those who helped in the preparation of this volume. We should particularly like to acknowledge the help of Piers Millett, who compiled the papers, set them into camera-ready format and produced the index and Dr. Simon Whitby who made the final changes to the manuscript. Any remaining errors are, of course, our responsibility. Malcolm R. Dando Cyril Klement Marian Negut Graham S. Pearson IX...

It is only with the ending of the Cold War that the issue of environmental hazards at many former nuclear testing sites around the world has attracted international scientific interest. This book discusses the environmental, ecological, and health problems associated with nuclear testing. Topics treated include dose assessment, risk, speciation and transport of radionuclides, measurement and separation of radionuclides, and remedial options. The nuclear test sites examined include the Semipalatinsk Nuclear Test Site (Kazakhstan), the Nevada test Site (USA), the Pacific atolls, and the...

There is increasing concern over the possible use of biological weapons. If they are used, an attack will manifest as a disease outbreak among humans, animals or plants. It is thus important to be able to distinguish between natural disease outbreaks and the result of such an attack. The bok discusses the scientific and technical means available to investigate this question and then goes on to consider the agents of concern. The book concludes with a look forward to future developments.

FRANCIS W. HOLM 30 Agua Sarca Road, Placitas, New Mexico 1. Overview The North Atlantic Treaty Organization (NATO) sponsored an Advanced Research in Prague, Czech Republic, on October 13-15, 1997, to collect and Workshop (ARW) study information on effluents from alternative demilitarization technologies and to report on these fmdings. The effluents, orprocess residues, identified for assessment at the workshop are generated by systems that have been proposed as alternatives to incineration technology for destruction of munitions, chemical warfare agent, and associated materials and debris....

The Advanced Research Workshop in Bucharest from 20. to 22. 04. 1998 covered a broad spectrum of medical and pharmaceutical approaches dealing to maintenaning and restoring of the health of civilians and military personnel exposed to ionizing radiation or biological or chemical agents. The current capabilities and future perspectives for protection against NBC hazards were analyzed from an interdisciplinary perspective. In this context the planning of medical support operations was addressed as were aspects of practical medicine and forwardlooking scientific approaches. The main areas covered...
