非人类物种辐射影响评价中参考生物筛选及应用

Selection of Reference Organisms and Primary Assessment of Radiological Impact of AP1000 on Non-human Species

内陆核电建设对非人类物种电离辐射的影响逐渐为人们所重视．环境影响评价报告中也对生物的辐射影响提出了明确要求。参考生物作为评估的基础．目前相关的研究还很少．也没有明确的选择和确定方法。同时针对我国三代核电发展的主要机型AP1000,其液态排放源项对参考生物电离辐射影响评价的数据也很匮乏。本文根据国际上对于参考生物的研究成果．提出了参考生物的筛选指标体系，并以彭泽核电厂址为参考，通过现场实验调查及查阅相关文献结果，确定彭泽核电厂址的主要参考生物，同时根据参考生物确定AP1000机型的水生生物电离辐射影响评价相关数据，进行辐射影响评价。评价结果表明，筛选的参考生物合理．AP1000评价数据能满足后续内陆核电厂环境影响评价的需要。

The radiological impacts on no n-human species due to the inland nuclear power plant construction were emphasized by people gradually. And it was also required in environmental impact statement. The studies of reference animals and plants as the basis of dose models were comparatively less and there were not clear selection methods. Meanwhile, for the third generation of nuclear power plant of China AP1000, there were also fewer researches on radiological impact of liquid effluent, and related data were quite less. According to the results of international researches and some selection guidelines, this paper developed a framework of reference organisms＂ selection index, and developed a set of data used in assessment of radiological impacts on aquatic organisms caused by the liquid effluent of nuclear power plant AP1000. The results showed that reference animals and plants selected by these index and the data set for AP1000 was suitable in assessment.
