Short summary
To better understand the impact of the Fukushima accident on commercial marine species, neon flying squid samples obtained from the NW Pacific in Nov 2011 were analyzed for a range of radionuclides. Elevated levels of Cs-134 and Ag-110m from the Fukushima accident were found in the samples, with an extremely high concentration ratio for Ag-110m. However, the radiological dose for squid living in the study area, and for human consumers of these squid, was far below the recommended dose limits.
