EVALUATION OF A TRANSURANIC COMPONENT IN REACTOR DERIVED RELEASES FROM FUKUSHIMA DAI-ICHI TO THE MARINE ENVIRONMENT

The incident at Fukushima Dai-ichi on March 11, 2011 was the consequence of several events (earthquake, tsunami, equipment failures, etc.) and led to the release of radioactive contaminants into the atmosphere and ocean. Although the specific details regarding the mechanism and/or the extent of radioactivity released to the environment are lacking, significant levels of fission products such as 131I, 134Cs, and 137Cs have been observed in the vicinity of Fukushima. As part of a research cruise in June, 2011 to study the problem, we received water samples collected between 30 and 600 km offshore. The main objective of our work is to determine the presence of/characterize a transuranic component in the reactor releases. Specifically, we are in the process of evaluating the levels of 237Np and Pu isotopes in selected samples from the cruise with a focus on the surface waters. Depending on the levels present, the measured isotopic composition should be diagnostic in resolving reactor derived contamination from background levels associated with global fallout. We will report our findings and compare them to other available data sets.
