Tokyo Shimbun reported on a finding that cardboard boxes containing heat insulators and drainage materials contaminated with low-level radiation are currently being stored at Yokosuka Naval Base, noting that the toxic waste was generated when the USS Ronald Reagan and other Yokosuka-based U.S. warships took part in “Operation Tomodachi” off the coast of Tohoku right after the 3/11 disaster. The contaminated equipment was removed during maintenance and unloaded from the vessels by this January and has been put in storage. The level of radiation is extremely low and poses no threat to human health. Arrangements will be made by the GOJ to dispose of the equipment properly.
