 note = {A technique to determine concentrations of 32P, 33P and 7Be in different forms, that is, dissolved and particulate forms, in the upper ocean was developed.  By using a large volume in situ filtration and concentration system (LV-FiCS), several tons of seawater at different depths were filtered concurrently through two kinds of filters.  The dissolved radionuclides were concentrated onto adsorbents in the LV-FiCS.  The radionuclides obtained were further purified by precipitation and ion exchange chromatography, and quantified by gamma spectrometry and ultra-low level liquid scintillation counter measurements.  The technique was used with good results in a coastal area of Ibaraki, Japan.},
