Karst Bauxites: Bauxite Deposits on Carbonate Rocks presents a comparison of bauxite regions using mathematical statistics methods. This book is divided into eight chapters that highlight the quantitative processing and assessment of the information available for bauxites. The opening chapters present observational and analytical evidence concerning karst bauxite, with particular emphasis on Hungarian bauxite deposits. The typical features of bauxites are analyzed from a variety of aspects and results from different bauxite regions are compared. Other chapters consider the feature of metamorphosed karst bauxites. The remaining chapters discuss the conditions of formation of karst bauxites and with the factors controlling their geographic and stratigraphic distribution. This book will prove useful to geologists, mineralogists, and researchers.

Gamma-ray spectrometry is a key technique in the study of the decay of radioactive materials. Used by scientists from a wide range of disciplines, problems can be encountered by the inexperienced user because there is a deceptive simplicity in gamma-ray measurements which can hide significant pitfalls. To resolve this situation, the authors of Practical Gamma-Ray Spectrometry have drawn on many years of teaching experience to produce this uniquely practical volume, giving comprehensive coverage of the whole gamma-ray detection and spectrum analysis processes. Discussions of the origin of gamma-rays and the issue of quality assurance in gamma-ray spectrometry are also included. Practical Gamma-Ray Spectrometry is written with the user in mind and has the following benefits: * Mathematics are kept to a minimum throughout. * No previous knowledge of nuclear matters or instrumentation is assumed. * Detectors and their associated electronic systems are discussed. * Fault-finding guide ensures that any problems can be sorted out with the minimum of fuss. Practical Gamma-Ray Spectrometry will enable all those involved with radioactivity measurements to get the most from their equipment. It will also be of great value to teachers and students in departments where radioactivity is studied, such as physics, chemistry, environmental biology, archaeometry and radiochemistry.

Volume 38 of Reviews in Mineralogy provides detailed reviews of various aspects of the mineralogy and geochemistry of uranium. We have attempted to produce a volume that incorporates most important aspects of uranium in natural systems, while providing some insight into important applications of uranium mineralogy and geochemistry to environmental problems. The result is a blend of perspectives and themes: historical (Chapter 1), crystal structures (Chapter 2), systematic mineralogy and paragenesis (Chapters 3 and 7), the genesis of uranium ore deposits (Chapters 4 and 6), the geochemical behavior of uranium and other actinides in natural fluids (Chapter 5), environmental aspects of uranium such as microbial effects, groundwater contamination and disposal of nuclear waste (Chapters 8, 9 and 10), and various analytical techniques applied to uranium-bearing phases (Chapters 11-14). This volume was written in preparation for a short course by the same title, sponsored by the Mineralogical Society of America, October 22 and 23, 1999 in Golden, Colorado, prior to MSA's joint annual meeting with the Geological Society of America.

Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.

Handbook of Radioactivity Analysis: Radiation Physics and Detectors, Volume One, and Radioanalytical Applications, Volume Two, Fourth Edition, is an authoritative reference on the principles, practical techniques and procedures for the accurate measurement of radioactivity - everything from the very low levels encountered in the environment, to higher levels measured in radioisotope research, clinical laboratories, biological sciences, radionuclide standardization, nuclear medicine, nuclear power, and fuel cycle facilities, and in the implementation of nuclear forensic analysis and nuclear safeguards. It includes sample preparation techniques for all types of matrices found in the environment, including soil, water, air, plant matter and animal tissue, and surface swipes.Users will find a detailed discussion of our current understanding of the atomic nucleus, nuclear stability and decay, nuclear radiation, and the interaction of radiation with matter relating to the best methods for radionuclide detection and measurement. - Spans two volumes, Radiation Physics and Detectors and Radioanalytical Applications - Includes a much-expanded treatment of calculations required in the measurement of radionuclide decay, energy of decay, nuclear reactions, radiation attenuation, nuclear recoil, cosmic radiation, and synchrotron radiation - Includes the latest advances in liquid and solid scintillation analysis, alpha- and gamma spectrometry, mass spectrometric analysis, gas ionization and nuclear track analysis, and neutron detection and measurement - Covers high-sample-throughput microplate techniques and multi-detector assay methods
