Series: Proceedings series (International Atomic Energy Agency). VICL 96-00142 Printed By the IAEA in Austria March 1996 STI/PUB/970 FOREWORD In recent years isotope applications in hydrology and water resources assess­ ment have reached a level of maturity. Adequate investigations have been carried out to provide sufficient examples for practical applications in comBination with other hydrological methods. The IAEA contriButed to this development through field projects implemented in MemBer States within the framework of the Agency’s Tech­ nical Co-operation programme. At present, the thrusts of the IAEA involvement are towards improved management of water resources in regions suffering from water scarcity, assessment of human impact on water resources, e.g. water pollution, and exploration and management of geothermal resources. Lately, novel isotope Based techniques have Been evolving from specialized laBoratories. While the techniques have emerged, efforts need to be concentrated on more practical work to accomplish a visiBle impact on water resources management. These trends and challenges are reflected by the scientific contriButions to the International Symposium on Isotopes in Water Resources Management, held from 20 to 24 March 1995 in Vienna. The main themes of the symposium were ground­ water resources management, with aBout two thirds of the contriButions addressing origin and recharge of groundwater, groundwater dynamics and pollution, modelling approaches, and geothermal and palaeowater resources. The remaining third of the contriButions were concerned with surface water and sediments, unsaturated zones and methodological aspects. On the occasion of World Water Day, 22 March, a spe­ cial session was held, with speeches By representatives from UNESCO, the govern­ ment of the host country and from the IAEA, as well as an address By the International Association of Hydrological Sciences. These proceedings contain the 43 papers presented and the extended synopses of over 100 poster presentations. It is hoped that they will contriBute to widespread integration of isotope techniques in projects tackling water and environmental proBlems, and also foster further developments in isotope hydrology.

  • Chlorine Stable Isotopes in Sedimentary Systems: Does Size Matter?
    Chlorine stable isotopes in sedimentary systems: does size matter? Max Coleman Jet Propulsion Laboratory, Caltech, Pasadena, California, USA ABSTRACT: Stable isotope abundances vary because of size (atomic mass) differences. The chlorine stable isotope system was one of the first described theoretically, but had a slow, disappointment-strewn develop- ment, relative to other elements. Method improvement gave only small, but significant, differences (-1 %.) in compositions of geological materials. Eventually, brines and groundwater chlorides gave larger differences (-5%0). Physical processes like diffusion and adsorption, probably are the main controls of groundwater com- positions. In contrast, the processes producing brine compositions are still enigmatic and need further work for full understanding. Recent work on anthropogenic groundwater contaminants (chlorinated aliphatic hy- drocarbons and perchlorate) shows variations resulting from manufacturing processes; implying possibilities of tracing sources. However, they are subject to microbial degradation, producing much larger fractionations (115%0),but therefore offering better possibility of monitoring natural attenuation. So atomic size is important to give isotopic fractionation and the size of fractionation matters, allowing observation of otherwise unde- tectable processes. lecular and atomic weights by weighing the gases and relating them to the weight of hydrogen.

  • Appendices D Through I
    Appendix D Operation & Maintenance Appendix D. Operation and Maintenance Plan Operation and Maintenance Plan This document presents the operation and maintenance (O&M) plan for Western Area Power Administration’s (Western) Sierra Nevada Region (SNR) transmission line systems. 1.0 Inspection/System Management In compliance with Western’s Reliability Centered Maintenance Program, Western would conduct aerial, ground, and climbing inspections of its existing transmission infrastructure since initial construction. The following paragraphs describe Western’s inspection requirements. Aerial Inspections Aerial inspections would be conducted a minimum of every 6 months by helicopter or small plane over the entire transmission system to check for hazard trees1 or encroaching vegetation, as well as to locate damaged or malfunctioning transmission equipment. Typically, aerial patrols would be flown between 50 and 300 feet above Western’s transmission infrastructure depending on the land use, topography, and infrastructure requirements. In general, the aerial inspections would pass over each segment of the transmission line within a one-minute period. Ground Inspections Annual ground inspections would check access to the towers/poles, tree clearances, fences, gates, locks, and tower hardware, and ensure that each structure would be readily accessible in the event of an emergency. They would allow for the inspection of hardware that would not be possible by air, and identify redundant or overgrown access roads that should be permanently closed and returned to their natural state. Ground inspections would typically be conducted by driving a pickup truck along the ROW and access roads. Detailed ground inspections would be performed on 20 percent of all lines and structures annually, for 100 percent inspection every 5 years.

  • 12 Natural Isotopes of Elements Other Than H, C, O
    12 NATURAL ISOTOPES OF ELEMENTS OTHER THAN H, C, O In this chapter we are dealing with the less common applications of natural isotopes. Our discussions will be restricted to their origin and isotopic abundances and the main characteristics. Only brief indications are given about possible applications. More details are presented in the other volumes of this series. A few isotopes are mentioned only briefly, as they are of little relevance to water studies. Based on their half-life, the isotopes concerned can be subdivided: 1) stable isotopes of some elements (He, Li, B, N, S, Cl), of which the abundance variations point to certain geochemical and hydrogeological processes, and which can be applied as tracers in the hydrological systems, 2) radioactive isotopes with half-lives exceeding the age of the universe (232Th, 235U, 238U), 3) radioactive isotopes with shorter half-lives, mainly daughter nuclides of the previous catagory of isotopes, 4) radioactive isotopes with shorter half-lives that are of cosmogenic origin, i.e. that are being produced in the atmosphere by interactions of cosmic radiation particles with atmospheric molecules (7Be, 10Be, 26Al, 32Si, 36Cl, 36Ar, 39Ar, 81Kr, 85Kr, 129I) (Lal and Peters, 1967). The isotopes can also be distinguished by their chemical characteristics: 1) the isotopes of noble gases (He, Ar, Kr) play an important role, because of their solubility in water and because of their chemically inert and thus conservative character. Table 12.1 gives the solubility values in water (data from Benson and Krause, 1976); the table also contains the atmospheric concentrations (Andrews, 1992: error in his Eq.4, where Ti/(T1) should read (Ti/T)1); 2) another category consists of the isotopes of elements that are only slightly soluble and have very low concentrations in water under moderate conditions (Be, Al).

  • Summary of North American Blancan Nonmarine Mollusks1
    MALACOLOGIA , 1966, 4(1): 1-172 SUMMARY OF NORTH AMERICAN BLANCAN NONMARINE MOLLUSKS1 D. W. Taylor U. S. Geological Survey, and Research Associate, University of Michigan Museum of Zoology, Ann Arbor, Michigan, U. S. A. ABSTRACT All known North American nonmarine mollusks of Blancan (late Pliocene and early Pleistocene) age have been here fitted into the available framework of associated fossils, physical stratigraphy and radiogenic potassium-argon dates. Many of the independently dated molluscan assemblages are so similar to other faunas that most of the fossils summarized can be assigned confidently to the Blancan age. These assignments permitted compilation of lists of last appear- ances of genera and families that are unknown during or after Blancan times. About 50-55 Blancan assemblages are known, and together with about 10-15 older or younger faunas included for convenience of discussion they are summarized under 57 local geographic headings (map, Fig. 1). For each local assemblage the following data have been given so far as possi- ble: location, previous references to mollusks, stratigraphic unit and most recent geologic maps, number of species of mollusks, mention of other fossils from the same locality or formation, age, institution where fossils are preserved, and most recent topographic maps. The detail of treatment varies widely, according to available information, progress of knowledge since previous liter- ature and the usefulness of new information. Lists of species are included usually only if the fauna is revised or first recorded in this paper, but the references to previous work are intended to be complete. The Blancan faunas from the Great Plains region (Nebraska, Kansas, Okla- homa, Texas), and from Arizona, are generally similar and include mainly widespread living species.

ISBN 91-554-6124-7 36 129 Two long-lived halogen radionuclides ( Cl, T1/2 = 301 kyr, and I, T1/2 = 15.7 Myr) have been studied by means of Accelerator Mass Spectrometry (AMS) at the Uppsala Tandem Labo- ratory. The 36Cl measurements in natural samples using a medium-sized tandem accelerator (∼1 MeV/amu) have been considered. A gas-filled magnetic spectrometer (GFM) was proposed for the separation of 36Cl from its isobar, 36S. Semi-empirical Monte-Carlo ion optical calculations were conducted to define optimal conditions for separating 36Cl and 36S. A 180° GFM was constructed and installed at the dedicated AMS beam line. 129I has been measured in waters from the Arctic and North Atlantic Oceans. Most of the 129I currently present in the Earth’s surface environment can be traced back to liquid and gaseous releases from the nuclear reprocessing facilities at Sellafield (UK) and La Hague (France).

  • The Isotope Effect: Prediction, Discussion, and Discovery
    1 The isotope effect: Prediction, discussion, and discovery Helge Kragh Centre for Science Studies, Department of Physics and Astronomy, Aarhus University, 8000 Aarhus, Denmark. ABSTRACT The precise position of a spectral line emitted by an atomic system depends on the mass of the atomic nucleus and is therefore different for isotopes belonging to the same element. The possible presence of an isotope effect followed from Bohr’s atomic theory of 1913, but it took several years before it was confirmed experimentally. Its early history involves the childhood not only of the quantum atom, but also of the concept of isotopy. Bohr’s prediction of the isotope effect was apparently at odds with early attempts to distinguish between isotopes by means of their optical spectra. However, in 1920 the effect was discovered in HCl molecules, which gave rise to a fruitful development in molecular spectroscopy. The first detection of an atomic isotope effect was no less important, as it was by this means that the heavy hydrogen isotope deuterium was discovered in 1932. The early development of isotope spectroscopy illustrates the complex relationship between theory and experiment, and is also instructive with regard to the concepts of prediction and discovery. Keywords: isotopes; spectroscopy; Bohr model; atomic theory; deuterium. 1. Introduction The wavelength of a spectral line arising from an excited atom or molecule depends slightly on the isotopic composition, hence on the mass, of the atomic system. The phenomenon is often called the “isotope effect,” although E-mail: [email protected]. 2 the name is also used in other meanings.
