摘要
In order to assess the radioactive impact of Fukushima Incident on the coastal environment of Dapeng Peninsula, Shenzhen, China, combining accelerator mass spectrometry with epithermal neutron activation analysis, we measured the 129 I/ 127 I ratios and 129 I levels in surface seawater, oyster ( Ostrea gigas ) and kelp ( Sargassum henslouianum ). The results showed that the influence of Daya Bay Nuclear Power Base was ignorable to local environment, but the Fukushima Incident had caused significant increase of 129 I levels in oyster ( P < 0.001) and kelp ( P < 0.05) from Dapeng Peninsula between Jun-2011 and Apr-2012. However, the 129 I levels in oyster and kelp were far below the guideline given by Codex Alimentarius Commission and would not cause immediate harm to the health of local residents.
