UPDATE, 10:00 am, Thursday, The International Atomic Energy Agency has reported that levels of Cesium-137 in areas outside the emergency evacuation zone (especially near Iitate Village, 40 kilometers—24 miles away) are more than twice as high than levels the Soviets established for relocation from the Chernobyl area. The IAEA said cesium levels are up to 3.7 megabecquerels per square meter (MBq/sq. m) in that area. Soviet guidelines required relocation when Cesium levels reached 1.48 MBq/sq. m. This is adding to pressure on the Japanese government to expand the evacuation zone.
