Residents were asked to move out within a month. The govern- ment will review both zones at a future date. *As of April 29, 2011 Soil shows low levels of radioactive contamination. Contamination levels could lead to radiation exposure exceeding what Japan deems acceptable over the course of a year. MAIN EVACUATION ZONE Established on March 12, the zone covers a 12.4-mile radius from the plant. Residents have only been allowed back for short supervised visits to retrieve some small possessions. GROUND CONTAMINATION* On March 15 winds shifted, and a rainstorm showered the toxic plume over communities northwest of the plant. FUKUSHIMA FALLOUT The earthquake and tsunami of March 11 triggered a disaster at the Fukushima Daiichi nuclear plant. Cooling systems failed, leading to a meltdown of nuclear fuel and the release of radioactivity into the environment. Since then more than 70,000 residents have been ordered to leave their homes.
