Biological samples of Isotope concentrations of Cesium 134 and 137, Silver 110m, and Potassium 40 from cruise KOK1108 in June 2011 in the Western equatorial Pacific and Kurushio Extension (Fukushima Radionuclide Levels project)

<p>Counts and concentrations of Cs134, Cs137, Ag110m, and K40 detected in zooplankton and small fish samples are reported. Samples were collected as part of a radioecological study of biota in order to assess the impact of radiation leaks from the Fukushima Daiichi nuclear power facility, damaged by a March 11, 2011 earthquake and tsunami. Radionuclide results were determined from high purity germanium detectors and calibrated against IAEA standards as described in Buesseler et al. (PNAS, 2012).</p>
