深圳大鹏半岛沿岸海水中129I的分布特征和来源
The distribution and source apportionment of 129I in coastal seawater of Shenzhen Dapeng Peninsula
摘要
Abstract
For exploring the radioactively ecological impact on the surrounding ocean environment caused by the long-lived radionuclide iodine-129( 129I) , which is generated and may be discharged into the environment during the operation process of Guangdong Daya Bay nuclear power station and Ling Ao nuclear power station, epither-mal neutron activation analysis and accelerator mass spectrometry have been utilized to analyze the concentrations of 127I and 129I in the seawater samples along Dapeng Peninsula, where Daya Bay Nuclear Power base is located. The results show that the concentration of 129I (370.9 × 106/L) and the N( 129I)/JV( 127I) ratio (37.4× 10-10) reach maximum in the seawater near the drain of nuclear power station, whereas both of them decrease to the radiation background level in the area 5 km away, indicating that the impac of 129I from the nuclear power plant on surrounding ocean environment is little. In this sea area 129I mainly comes from the global fallout released by the atmospheric nuclear tests and nuclear fuel reprocessing plants. The radioactive risk to the human body at itscurrent level can be ignored.关键词
