방사성 물질의 해양누출 사고에 대한 체계적인 관리 시스템 구축방안

Abstract

Highly radioactive materials have been released into the ocean at the Fukushima Nuclear Power Plant, following the Tohoku earthquake and tsunami on 11 March 2011. The Japanese leakage accident became one of the most serious global issues. It especially draws concern from Koreans who fear possible direct radiation exposure due to their geographic closeness and distrust Japanese government information on radiation. {According to a report published on 29 October 2011 by a French research institute, the pollution of the Pacific Ocean was probably 30 times bigger than the Tokyo Electric Power Company reported in May 2011.} Radioactive substances usually spread through air and oceans, and can be accumulated in marine life and eventually in human body. To minimize the potential radiation exposures and long-term effects on human health, we propose to design and establish an integrated crisis management system. Under this system, sea water and biological samples will be periodically and extensively collected to detect and identify spatial and ecological pathways of radioactivity. Together with data from satellites, the collected data will be utilized to forecast the magnitude and dispersion of radioactivity by developing a bio-physical coupling model that combines general oceanic circulation and ecological models.
