摘要

Debris from Japan's Fukushima Dai-Ichi nuclear power plant, which was severely damaged after the earthquake and tsunami in March 2011, will begin to wash up on U.S. shores later this year. Many have asked whether the debris will pose a radiation risk, and researchers from Oregon State University (OSU) have found the simple answer to be no.Most of the discharge that was of concern was radionuclides of iodine and cesium, deposited on widely dispersed, floating marine debris. Most of the iodine will have disappeared due to radioactive decay, and the cesium washed off and diluted in the ocean, the researchers said in February. But not all of the debris that reaches the Pacific Coast of U.S. and Canadian shores will be harmless.
