大亚湾周围海域几种水生生物的辐射剂量估算

Four Non-human Species Radiation Assessment in Daya Bay

提出了一个包括源项、照射途径、核素来源、剂量估算以及与释放限值比较等在内的非人类物种辐射剂量的评估框架;并选择大亚湾核电站所在的自然生态系统为研究对象,以对虾、黑鲷、毛蚶和小球藻4种水生生物为代表,建立它们的剂量学模型,并使用DOE GRADED和EU ERICA的非人类物种剂量计算软件以及Monte-Carlo方法对其剂量进行计算,对大亚湾的辐射环境提供评估参考。

Radiation protection of non-human species is an important extension of radiation protection. This articale established a framework including a source term, exposure pathway, source of radionuclide, dose estimation and comparison with the release limit of non-human species. Selected four reference organisms of Penaeus, Scapharca subcrenata, Sparus macrocephalus and Chlorella on the basis of the international reference biological selection criteria, established dosimetry model, and used the software of DOE GRADED, EU ERICA and Monte-Carlo method to calculate the human species dose rate and assessed the radiation environment of Daya Bay.
