Pressure Stabilizes in Japan Reactor, 2 Survivors Found VOA News March 20, 2011 Teams of government and nuclear specialists at the emergency rescue headquarters analyze data from the leaked radiation from the Fukushima nuclear facilitiesin Fukushima, Japan, March 19, 2011 Photo: AP Teams of government and nuclear specialists at the emergency rescue headquarters analyze data from the leaked radiation from the Fukushima nuclear facilitiesin Fukushima, Japan, March 19, 2011 In another development, the Japanese government says elevated levels of radiation have been found in milk and spinach near the crippled nuclear power plant in Fukushima prefecture and in a shipment of fava beans on the island of Taiwan Chief Cabinet Secretary Yukio Edano told reporters Saturday that although radiation levels exceeded government safety standards, the tested food does not pose an immediate health risk. He said the government will decide Monday whether to ban sales and export of food products from the area. But, a statement from the International Atomic Energy Agency says radioactive iodine can pose a short-term health risk if ingested, particularly for children. Government health officials said Saturday that radioactive iodine was found in drinking water from Fukushima prefecture on Thursday, at levels above government safety limits. Kyodo news, citing Japan's Health Ministry, says the iodine levels then fell. There was no explanation in the report as to why the information was not released sooner. The government also said trace amounts of radioactive substances have been detected in tap water in Tokyo and other areas, but at levels that are not dangerous to human health. In a Twitter message Saturday, the U.S. ambassador to Japan, John Roos, said he told Prime Minister Naoto Kan that the United States is committed to helping Japan contain the crisis and rebuild the nation. Roos also said the workers at Fukushima are taking "heroic actions" and that the U.S. will provide whatever it can to help them succeed. The risk of radiation poisoning has already forced the evacuation of more than 200,000 people who lived within 20 kilometers of the reactors. Many are in makeshift shelters, with inadequate food, water and other supplies, in frigid winter weather. Japan raised the severity rating of the disaster from 4 to 5 on the 7-point international nuclear event scale. Level 5 signals an accident with wider consequences, including some release of radioactive material, with a high probability of significant public exposure.
