Spatial variations of low levels of 134Cs and 137Cs in seawaters within the Sea of Japan after the Fukushima Dai-ichi Nuclear Power Plant accident

Our method based on low background γ-spectrometry enabled the measurement of low radiocesium concentrations in only 20L of seawater. In May 2011 after deposition of radiocesium, 134Cs concentration in surface water within the Sea of Japan was confirmed to be significantly small (
