Radiochemical Studies on "Bikini Ashes"(March1, 1954).PartI.

Studies on the radiological contamination of fishes. III. Radiochemical studies of contaminated fish.

The distribution of radioactivity in fish bodies had been made clearly by our observations on•gShunkotsu Maru•h. It was also observed that the radioactivity in one organ of a fish was quite different from that of another.. However, the radioactive elements contained in fish bodies were left un-identified. The present work was undertaken to meet the urgent necessity of identification of the radi...

Radiochemical Studies of the Transactinide Element, Rutherfordium (Rf) at JAERI

Radiochemical studies of element 104, rutherfordium (Rf), at JAAERI (Japan Atomic Energy Research Institute) are reviewed. The transactinide nuclide 261Rf has been successfully produced in the reaction 248Cm(18O, 5n) at the JAERI tandem accelerator. The excitation function of the reaction has been measured with a rotating wheel catcher apparatus and the maximum production cross section has been...

Radiochemical Analysis of Water

This report describes the methods and procedures used by the U.S. Geological Survey Tritium Laboratory to analyze natural waters for tritium activity. Samples having low activity are electrolytically enriched in cells with nickel and steel electrodes, and their tritium concentration is subsequently determined by liquid scintillation and gas phase counting techniques. Samples having high tritium...
