Marine radioactivity monitoring is an important scientific basis for the marine nuclear safety. The effluent released to marine and marine monitoring after Japan's Fukushima Daiichi accident were briefly reviewed. The marine radioactivity monitoring work were introduced, including monitoring contents, monitoring methods, monitoring equipment and monitoring data to guide nuclear emergency response. Recommendations on the development of national marine radioactivity detection technology were proposed.
