Japan led the severity of the crisis of its crippled nuclear plant on Tuesday, the list is on par with the Chernobyl disaster of 1986, citing the loss of cumulative radiation pollute the air, tap water, vegetables and water sea.
Japan, the nuclear safety authorities said the rating was increased to 5-7 - the highest level on an international scale monitors the International Atomic Energy Agency - a new evaluation system of the radiation losses Fukushima Dai-ichi since was turned off March 11 tsunami.
The new classification is a "serious accident" that includes widespread effects on the environment and health, according to the IAEA in Vienna.
However, Japanese officials have downplayed the health effects to date. It said the amount of leakage on the tenth floor of Fukushima of the emitted radiation in the Chernobyl disaster, while recognizing that eventually could exceed the Chernobyl emissions, if the crisis continues.
"This confirms that a disaster is very important. Sorry for the public, people living near the nuclear complex and the international community for having caused a serious accident," said Chief of Staff Yuki Edan.
Edan but told reporters that "there is no direct health damage" to the extent of the crisis. "The accident itself is really bad, but we put our priority in order not to damage the health."
Hironobu Unesaki, a nuclear physicist Kyoto University Research Reactor Institute, said the amendment would not worry, he had to do the whole release of radiation and had a direct risk to health. He said that most of the radiation was released at the beginning of a crisis and that the reactors are still largely intact vessels surrounding the heart.
The change was "not directly related to the effects of environment and health," said Unesaki. "From all of measurement data, it is quite under control. That does not mean that a large amount of emissions are continuing."
Review the day came after the government increased the five communities in May the list of places people should go out and avoid prolonged exposure to radiation. 12 nautical miles (20 kilometers) radius had already been cleared around the plant.
replicas megaquake long after the magnitude 9.0 on March 11 have been prevented from working in the stabilization of the plant in Fukushima - after a 6.3 magnitude that caused the factory Tuesday operator Tokyo Electric Power Co. to remove temporary workers .
Officials of Japan Nuclear and Industrial Safety Agency said that the cumulative amount of radioactive particles in the atmosphere since the incident had reached levels that are applied to a level 7 incident. Other factors include damage to factory buildings and accumulated radiation levels for workers.
"We have improved the level of severity to 7, as the impact of the leakage radiation was released into the air, vegetables, tap water in the ocean," said Minoru Oogoda official NISA.
The review is based on the duplication of assessments and data on radiation leaks of iodine-131 and cesium-137, the spokesman said Hidehiko Nishiyama NISA.
"We declined to make any statements until we have reliable data," Nishiyama said. "The notification is done now, because it was possible to examine and review the accumulated data evaluated in two different ways," he said, referring to measures of Nisa and Japan Nuclear Safety Council.
Nishiyama noted that, unlike the Chernobyl explosion was not in the core of the plant in Fukushima Dai-ichi, even if the explosions of hydrogen.
"In that sense, this situation is completely different from that of Chernobyl," he said.
He said the amount of radiation leakage from the plant in Fukushima Dai-ichi Nuclear was about 10 percent of the Chernobyl accident.
However, the plant operator TEPCO is still estimating the total amount of radioactive material that could be released, the company spokesman, said Junichi Matsumoto. He acknowledged that if the leak continues, the amount of radioactivity released could exceed the amount emitted by Chernobyl.
The company, under fire for his handling of the accident and its readiness before 11 March earthquake and tsunami, apologized second Tuesday.
"I humbly accept this. We deeply apologize for causing enormous problems for those living near the nuclear complex and the people of the prefecture," TEPCO spokesman Naoki Tsunoda.
Chernobyl, Ukraine, a reactor exploded on April 26, 1986, spewing a cloud of radiation over much of the northern hemisphere. An area of about 19 miles (30 kilometers) around the plant was declared uninhabitable, although some plant workers still live there for short periods and a few hundred people have returned despite the promotion of government to maintain away.
In 2005, the Chernobyl Forum - said fewer than 50 deaths could be confirmed as being associated with Chernobyl - a group comprising the International Atomic Energy Agency and several United Nations groups. He also said that the number of deaths related to radiation among the 600,000 people who helped to cope with the consequences of the accident was finally around 4,000.
Health agency of the United Nations says about 9,300 people are likely to die of cancers caused by radiation. Some groups, including Greenpeace, have put the number 10 times higher.
The plant in Fukushima was damaged in a massive tsunami on 11 March, which hit the cooling systems and backup diesel generators, which led to explosions and fire three reactors in the quarterfinals, which were during regular maintenance and has been emptied of fuel.
The magnitude 9.0 earthquake that caused the tsunami was immediately arrested the three reactors, but the carrots overheating and lack of cooling functions leading to further damage.
The engineers have pumped into the water damaged the reactors to cool them, but the losses have led to a combination of tons of contaminated, radioactive water that prevented workers to carry out further repairs.
One month after the disaster, more than 145,000 people still living in shelters. The earthquake and tsunami is believed to have killed over 25,000 people, but many bodies were swept into the sea, and over half of those were killed are still missing.
