TOKYO - developed new characters on Friday that parts crippled nuclear power station Fukushima Daiichi were so damaged and contaminated that it would be even more difficult to bring the plant under control soon.
At the same time, Japanese began officials who encourage people to evacuate a larger band of territory around the complex.
In an interview with a national audience at a press conference on Friday night, two weeks after the earthquake of magnitude 9.0 and the devastating tsunami, which it followed Prime Minister Naoto Kan dodged a reporter of the question whether the Government was ordering a complete evacuation, said officials were simply follows the recommendation of the Commission for Japan nuclear safety.
"The situation requires more caution," Mr Kan, heavy and tired looking, said the nation. "Our measures are designed to prevent, that the circumstances worse." The authorities said she would now help people leave wanted the range of 12 to 19 miles outside the plant, and that they now "voluntary evacuation" promotion, from the area.
These people indoors, had stay March 15 get, while to evacuate the facility had ordered within a 12-mile radius. The United States has to remain at least 50 miles recommended its citizens.
Mr Kan said "The State of the system is still very precarious,". "We work hard to ensure that it not be worse." "We must ensure that it no further deterioration."
In a new sign of the contamination problem that said nuclear and industrial Agency on Saturday a sample of sea water taken Friday from a monitoring station in the work the level showed the iodine-131 to 50 becquerel per cubic centimeter - 1,250 times of the permitted.
Drink a half litre of water would be tantamount to getting a 1 milliSievert dose, the Agency said, as the amount that a person obtains a year from natural sources.
Hidehiko Nishiyama, Deputy Director of the Agency, said that he expected the iodine quickly, dilute to minimize the impact on wildlife, General and noted that fishing activities in the area was suspended after the Quake and tsunami.
A sign of the possible deterioration of the plant itself came to the reactor workers, the attempted, an electric cable with a pump in a turbine connect no. 3. building next to the reactor were injured when she entered into water, which was found significantly more radioactive than normal be. On Friday, officials and experts offered conflicting explanations of what wrong gegangen-but stressed all greater damage to the reactor systems and more pollution had earlier indicated it as officials.
Two workers were when poured water over their boots and said to their feet and ankles, officials burned and exposed to radiation. A third worker was not the same exposure higher boots and suffering.
As the affected workers, many of those are subcontractors of Tokyo electric power, who are paid a small daily wage for hours of work in dangerous conditions risk of their lives. They are sometimes ill-equipped and trained for their job.
On the Saturday concentrated to the workers to try, the lighting reactor No. 2 central control room, an important step towards the restoration of unity cooling system restore. You were once again pump prepare units, the No. 1, no. 2 and no. 3 after days with salt water to fresh water.
Said the National Institute of radiological sciences, that the radioactivity of the water, the the three injured workers in joined had 10,000 times the level normally in the coolant water was seen in the work. It said that the amount of radiation that the workers were intended, to the water exposed to have two to six Sieverts was.
Eight times, the new 250 milliSievert is even two Sieverts annual exposure limit value for workers in total be set in the days following the disaster; the previous limit was 100. Tokyo Electric officials said that water had been found with an equally high radiation in the reactor No. 1 building, reported the associated press.
Skin demands from two to six of Sieverts j. Brenner, Director of the Center for radiological research at Columbia University caused severe burns, according to Dr. David. But if these cans reach the whole body and not only the skin "You are a very high risk of dying," he said.
