Abstract

Using typical fish samples collected in the north Pacific on 2011 to 2012, adopting High Purity Germanium (High Purity Germanium) passive scale efficiency detect gamma spectrometer, radioactive nuclide 134Cs was detected in all samples. Using classification and sub-organs and other treatment methods to compare and analyses, we found that in 2011, the highest 134 Cs nuclide content is in the 155ø5'E, 42 ø 10' N stance, as high as 4.925 Bq kg-1; the lowest in 39 ø 51 '132 ø 44' E, N the waters of the sea, nuclide specific activity value does not exceed the bottom level. In the North Pacific ocean, the 134Cs's overall radionuclide content from south to north was decreasing. In 2012, the highest 134Cs nuclide content is in 58 'E, 43 ø 155 ø 34' N, 0.159 Bq kg-1; the lowest in 131 ø 47 'E 36 ø 50' N in sea waters position , the nuclide content in the high seas 134Cs showed a trend of increased distribution from west to east. From content distribution of two different tissues of the Neon flying squid, visceral is the highest enrichment of nuclide 134Cs and the head is lowest. According to the estimation results, the 134Cs Radionuclide concentrations and radiation increment now in the north Pacific are within an environmental safety concentration limits.
