Five weeks after Japan's Disaster, reports suggest worse, not improved conditions. It portends serious regional and global trouble ahead, besides what's already happened. On April 16, AP headlined "Radioactivity Rises in Sea off Japan Nuclear Plant", saying: "Levels of radioactivity have risen sharply in seawater near Fukushima, signaling the possibility of new leaks at the facility, the government said Saturday." The announcement followed a 5.9 level aftershock rocking the country early Saturday. So far, no additional damage reports were issued, however, seawater radioactive Iodine 131 spiked to 6,500 times above normal, up from 1,100 times Friday, and Cesium 134 and 137 rose nearly fourfold. Japan's Nuclear and Industrial Safety Agency (NISA) raised the possibility of worrisome new leaks, admitting that tracking them is "difficult." Nonetheless, they still claim no threat to humans or sea life, despite the numerous independent experts raising dire warnings of spreading global radiation, including plutonium, the most deadly substance known, since a microscopic speck is enough to cause cancer.
