AbstractAbstract
[en] Tritium concentrations were measured for river waters on two islands in Japan. Significant difference was observed on the distribution of tritium concentrations on both islands, the river water samples from the northern island had higher concentrations and the average was about twice compared to that from the southern island. Higher tritium concentration in precipitation and the larger area of the northern island would be responsible for higher tritium concentrations in river waters. (author) 7 refs.; 4 figs.; 2 tabs

AbstractAbstract
[en] As part of the evaluation of the environmental impact due to the nuclear facilities available at IPEN, the determination of the distribution coefficients of the radionuclides present in the 1988 source term is proposed. The first RN was Thorium since it is produced in the Uranium and Thorium purification plants. he distribution coefficients and the uptake were studies in pH s from 4.4 to 8.0, according to CETESB monthly reports in the last years. The 234 Th used as tracer was separated from a uranyl nitrate solution by ion exchange. The separation of the solid and liquid phases was carried out by filtration using a micro pore 0.45 μm filter. The activity was measured by using a Hp Ge detector from INTERTECHNIQUE model EGPC25, and the spectrum was analysed by a simplified version of the SAMPO program. The values of Kd obtained under these conditions ranged from 137 x 103 and 2.56 x 106 mL/g. (author)

AbstractAbstract
[en] It is of much current interest to determine the flow characteristics of fractures intersecting a wellbore in order to provide data in the estimation of the hydrologic behavior of fractured rocks. In particular the fluid inflow rates from the fractures into the wellbore are important quantities to measure. However often these inflows are at very low rates. In addition very often one finds that only a few percent of the fractures identified by core inspection and geophysical logging are water-conducting fractures, the rest being closed, clogged or isolated from the water flow system. A new method has been developed to locate water-conducting fractures and obtain fracture inflow parameters by means of a time sequence of electric conductivity logs of the borehole fluid. The physical basis of the analysis method is discussed. The procedure is applied to an existing set of data, which shows initiation and growth of nine conductivity peaks in a 900-m section of a 1690-m borehole, corresponding to nine waterconducting fractures intersecting the borehole. We are able to match all nine peaks and determine the flow rates from these fractures. A discussion is given on the applicability of this technique in the context of a borehole testing program.

AbstractAbstract
[en] The occurrence of relatively high concentrations of radionuclides in certain spring waters has been of interest to researchers on natural radioactivity and radioprotection including in Brazil. Twenty four springs known in the Pocos de Caldas plateau were analysed and investigated for their concentrations on U-238, U-234, Th-232, Th-230, Th-228, and Ra-226. The highest activity concentrations were found in waters from Aguas da Prata, in the rim of plateau, where values up to 2,4 Bq/l of Ra-226 were measured. (author)

A presenca de concentracoes relativamente altas de radionuclideos em aguas sbterraneas vem despertando o interesse de pesquisadores em radioatividade natural e radioprotecao. Foram determinadas as concentracoes de U-238, U-234, Th-232, Th-230, Th-228, Ra-228 e Ra-226 em vinte e quatro amostras de aguas minerais do Planalto de Pocos de Caldas. Os valores maximos observados correspondiam a amostras provenientes da cidade de Aguas da Prata, na borda do planalto, que continham ate 2,4 Bq/l de Ra-226. (autor)Original Title
