英文摘要：

This paper characterizes the types, trend and the potential of radiation contamination in the sea against the development of nuclear power stations. Combined with the present status of radioactive contamination and marine biodiversity in China seas, it is pointed out that non-human radiation protection should be considered on the bases of marine biodiversity protection. Besides, the reference species for marine radiation protection and some viewpoints on the work of marine radiation protection in China are proposed.
