Japan’s nuclear safety agency, NISA, says tests on Friday reveal that radioactive iodine levels have spiked 1,250 times higher than normal in sea water just offshore from the damaged Fukushima nuclear plant. Radioactive water has also been found in three of the six structures that house reactors there, and on Thursday, three workers were burned at reactor No. 3 when they stepped in a pool of “hot” water. They were exposed to radiation levels 10,000 times higher than usually found in a reactor. (Reuters)
