RADIONUCLIDE LEVELS IN THE CENTRAL PACIFIC OCEAN AFTER THE FUKUSHIMA DAIICHI NUCLEAR POWER PLANT ACCIDENT

The March 11, 2011 earthquake and tsunami made substantial damage to the Fukushima Daiichi nuclear power plant and as a result significant amounts of radioisotopes were released to the environment. As early as on March 22 the US EPA reported that RadNet air monitors in Hawaii detected isotopes consistent with the Japanese nuclear incident. Immediately after the incident we begin monitoring coastal and offshore seawater in Hawaii for cesium isotopes. We used a novel AMP-PAN resin that quantitatively sorbs cesium from large-volume seawater samples. After sorption, the resin was counted on a HPGe gamma-spectrometer to measure Cs-134 and Cs-137 activities. We will present results from surface ocean in coastal Guam and Hawaii, the Midway Islands, and station Aloha. We will also present our findings from a transect leading from Fukushima to Oahu which should help explain the spreading pattern of soluble radioisotopes such as cesium in the Pacific Ocean.
