The Mainichi Daily News Japan mdn.mainichi.jp/mdnnews/news/20110412p2a00m0na002000c.html 12 April 2011 Quote: Evacuation order expanded around crippled nuke plani The Japanese government, struggling to bring the crisis at the Fukushima No. 1 nuclear power plant under control, expanded the evacuation areas around the troubled facility on April 11. The government reviewed its order and expanded the evacuation zone beyond the previous 20-kilometer radius from the plant crippled by the March 11 earthquake and tsunami due to varying degrees of radiation contamination. “Symptoms will not appear suddenly if victims are exposed to a dose of 20 millisieverts of radiation a year. We expect affected residents to evacuate early but doing so in a hurry without minimum belongings would make their lives inconvenient,” said Haruki Madarame, chairman of the Nuclear Safety Commission of Japan, at a news conference on the revised evacuation order. The government designated areas subject to the expanded evacuation zone in light of the confirmed spread of radiation. Radiation spreads along with dust in the air. It is influenced by which way the wind blows and geography and does not necessarily spread in a concentric fashion. The level is at the low end of the range of 20 to 100 milisieverts set by the International Commission on Radiological Protection as the highest permissible residual dose over a year for the general public under emergency situations. The Nuclear Safety Commission recommended the evacuation order to the government based on international standards on April 10. Otsura Niwa, a professor emeritus of radiobiology at Kyoto University, said, “There will be almost no effects on health in the planned evacuation zones at the current level of dosage even if residents stayed there for another month. If residents plan to return to their houses, some districts will have to reduce radiation by removing surface soil.” end quote
