Recent photo of Unit 4, with workers (in white radiation suits, under girders) next to pool's surfaceJapanese diplomat Akio Matsumura has been warning about the risks of Fukushima Daiichi Unit 4's high-level radioactive waste storage pool failing (see photo, left), as due to another strong earthquake. Matsumura has worked with the former Japanese Ambassador to Switzerland, Murata, who has recently testified before the Japanese federal parliament, as well as written to Japanese Prime Minister Noda and U.N. Secretary General Ban Ki-Moon, urging international cooperation to address the dangers at Unit 4. Matsumura has devoted his homepage to dialogues with the likes of Bob Alvarez at Institute for Policy Studies, Gordon Edwards at Canadian Coalition for Nuclear Responsiblity, and Steven Starr with PSR, to better understand the situation and amplify the international warning.
