    An improved apparatus for the determination of krypton-85 and xenon-133 in an emergency situation (1988)

    Notizen: Abstract A simple and portable apparatus was developed for measurements of85Kr and133Xe that would be released into the atmosphere in an emergency situation of nuclear facilities. The method is based on cryogenic adsorption of these gases on charcoal followed by chromatographic separation from other gases. The85Kr and133Xe recovered from atmospheric air are determined separately by liquid scintillation counting. It takes about 1 hour for the stepwise determination of85Kr and133Xe. The atmospheric concentration of 3·10−3 μCi per m3 air (1.1·102 Bq/m3 air) is measurable for both nuclides with 20% counting error.

    Tritium concentrations of the deep sea-water in the Japan Sea and the Pacific Ocean (1988)

    Notizen: Abstract Tritium concentrations were determined for sea-water samples collected from the Japan Sea and the Pacific Ocean. In the Japan Sea, it was recognized that tritium was distributed around 2000 m in depth. This means that the vertical mixing of water mass is taking place. On the other hand, in the Pacific Ocean, the tritium concentration appears to reach zero at about 1000 m although more than 1 TU concentration are detected for samples collected from deeper water. Hypothetical origins of tritium in the deep water in the Pacific Ocean are discussed.
