AbstractAbstract
[en] The progress of research and development work and various activities of the Radiochemistry Division of the Bhabha Atomic Research Centre, Bombay, during 1974, are reported. The Division developed : (1) coulometric methods of determination of plutonium and uranium (2) titrimetric method of determination of uranium (3) analytical techniques for determination of metallic and non-metallic impurities in plutonium fuel for its quality control and (4) magnesium tracer techniques MAGTRAP based on isotope dilution and mass spectrometry for accounting of plutonium in a fuel reprocessing plant. An alpha tight 10,000 Ci hot cell has been commissioned and used for separating fission-produced 99Mo required for preparation of 99Tc generators for medical application. The Division fabricated: (1) a controlled potential coulometer for plutonium estimation (2) an assembly for fluorescence lifetime studies (3) an I.C. based coincidence/anticoincidence unit for use with low background β-counter and (4) photo-multiplier pre-amplifier for long distance applications. The work is continuing in the following areas: (1) process chemistry of neptunium (2) X-ray fluorescence analysis for uranium determination (3) in-line analytical technique for fuel reprocessing stream (4) antinide chemistry and (5) fission phenomena.

AbstractAbstract
[en] Concentrations of five rare earth elements (REE) were measured in clay samples of a deep bore hole comprising major aquifers of Pondicherry region, south India in order to investigate the geochemical variations among various litho-units. Clay samples from Cretaceous formation show distinct gray to black color whereas Tertiary deposits have clays with color varying from pale yellow to brown to gray. All measured REEs exhibit lower concentrations than Upper Continental Crust (UCC) average values. Large variations in REEs contents were observed in different sedimentary formations (Tertiary and Cretaceous). Chondrite normalized ratio of La/Lu and Eu/Eu* indicate that the clays are derived from weathering of felsic rock and possibly under humid climate. All the samples showed positive Eu anomaly in North American Shale Composite (NASC) normalized plot which shows plagioclase feldspar as the major contributor to these clays. Positive Eu anomaly is also an indication of reduced condition of the formation. (author)

AbstractAbstract
[en] In order to understand the mobility of uranium it is very important to know about its sorption kinetics and the thermodynamics behind the sorption process on soil. In the present study the sorption kinetics of uranium was studied in soil and the influence parameters to the sorption process, such as initial uranium concentration, pH, contact time and temperature were investigated. Distribution coefficient of uranium on soil was measured by laboratory batch method. Experimental isotherms evaluated from the distribution coefficients were fit to Langmuir, Freundlich and Dubinin-Raushkevich (D-R) models. The sorption energy for uranium from the D-R adsorption isotherm was calculated to be 7.07 kJ mol-1. The values of ΔH and ΔS were calculated to be 37.33 kJ mol-1 and 162 J K-1 mol-1, respectively. ΔG at 30 deg C was estimated to be -11.76 kJ mol-1. From sorption kinetics of uranium the reaction rate was calculated to be 1.6 x 10-3 min-1. (author)

AbstractAbstract
[en] The wild plant species occurring in the campus of the Bhabha Atomic Research Centre, Bombay, have been put on record. The plants collected and identified are maintained in a herbarium. The species collected are enumerated and the species under each family are arranged in the alphabetical order. The classification of Bentham and Hooker is followed with some modifications in the names of families which are adopted from recent works. (M.G.B.)

AbstractAbstract
[en] An indigenous technology for the production of 125I brachytherapy sources has been developed for the management of intraocular cancer. This indigenous method of producing 125I seeds represents a new paradigm, and a thorough quality evaluation of the seeds in accordance with Atomic Energy Regulatory Board (AERB) of India was carried to ensure their safety during therapy. In this current work, we describe an overview of our experience, the efforts made in establishing enviable quality analysis of 125I seeds to ensure their safety in episcleral plaque brachytherapy.

AbstractAbstract
[en] Bhabha Atomic Research Centre was established in 1950 and is engaged in: 1. Setting up research facilities. 2. Process development for various chemical and metallurgical needs of nuclear industry. 3. Production of nuclear instrumentation and more particularly high vacuum equipment. The first nuclear power station was built on turnkey-type by Americans and the second in collaboration with Canada, with the most responsibility handled by India. For the third, responsibility for design, construction and commissioning has been handled by Indians. Construction of heavy-water plants and a nuclear fuel complex for production of nuclear fuel has also proceeded. Transfer of technology from research and technology and development groups to manufacturing operation and project sites has taken place successfully
