Environmental Isotope Applications in Hydrology: an Overview of the Iaea's Activities, Experiences, and Prospects
نویسنده
چکیده
Development and applications of isotope methodologies in hydrology have been an integral part of the program component of the IAEA over the last three decades, within the framework of its overall activities related to peaceful nuclear applications. The use of environmental isotopes as a means of tracing water movement in the hydrology including surface and ground water is much of the Agency's work in this field. This paper provides an overview of the temporal and spatial variations of the above cited isotopes in precipitation based on the long-term data collected from the global network, and reviews the concepts and formulations of environmental isotope applications to specific problems in hydrology and hydrogeology. Results of a few case studies are provided to illustrate their use. Activities of the IAEA in this particular field, together with future prospective developments in the use of environmental isotopes in hydrology and environmental studies are briefly discussed.

Ancient Gold Mining Activities in India - An Overview
Gold was obtained through washing or panning of the river sands during initial periods of civilisation. With the advent of knowledge of metallurgical processing of ores it was recovered through mining of in-situ quartz reefs, and then from auriferous sulphide ores. The metal mining activities are evidenced in the form of large number of ‘ancient metal mines’ or ‘old workings’ and ‘placer mining...
