FILE – This 1986 aerial file photo of the reactor four at the Chernobyl nuclear plant in Chernobyl, Ukraine shows damage from an explosion and fire on April 26, 1986 that sent large amounts of radioactive material into the atmosphere. Japan raised the crisis level at its crippled nuclear plant Tuesday April 12, 2011, to a severity on par with the 1986 Chernobyl disaster, citing high overall radiation leaks that have contaminated the air, tap water, vegetables and seawater. Japanese nuclear regulators said they raised the rating from 5 to 7 _ the highest level on an international scale of nuclear accidents overseen by the International Atomic Energy Agency _ after new assessments of radiation leaks from the Fukushima Dai-ichi plant since it was disabled by the March 11 tsunami.
