Japan evacaa workers Fukushima reactor 2 of the high radioactivity

Growing concern about the nuclear plant in Fukushima 1, affected by the earthquake and tsunami of 11 March. In the reactor 2 were detected radiation levels well above normal, according to TEPCO, the company that operates the plant, forcing the evacuation of the technicians working to try to repair it.

Although at first instance was reported 10 million levels above normal, TEPCO has been reported in a subsequent press conference has erred in measurements. "There has been a confusion between iodine 134 and cobalt 56," said Sakae Muto, vice president of the company. TEPCO will conduct an analysis of radiation levels.

No osbtante, remains the evacuation of workers. The radioactive water inside the plant workers prevents the restoration of the cooling systems of nuclear power, which is essential to avoid fusion of the nuclei. Meanwhile, the IAEA haanunciado this morning that the reactor 1 has detected the presence of iodine 131, cesium 137 and cesium-134 at levels comparable to those of the zone of reactor 3 where three workers were injured on Thursday.

Rafael Grossi, deputy adjutant general of the International Atomic Energy Agency (IAEA), told this newspaper yesterday that the situation in central Fukushima is serious and that "any time" may be degraded. Also today, has been known that most Japanese citizens, 58%, suspended the government's response to the crisis that has damaged nuclear power plant in Fukushima I, while 39.3% expressed their approval, according to figures a recent survey by Kyodo News agency released today.

In addition, the Agency Japan Nuclear and Industrial Safety has reported this morning (Spanish time) that the levels of radioactive iodine in seawater collected in the vicinity of the nuclear power already exceeds Fukushima-1 at 1,850 times the legal limit . Samples taken Monday showed higher levels 1,250 times the limit.

Agency spokesman, Hidehiko Nishiyama, said that the leakage of the reactors are responsible for these high levels of radiation, because the water has reached the sea that had previously been stored in buildings that house the turbines. The number of tsunami victims New information that is attached to the new data of casualties that the Japanese police provided daily.

The final balance figure of 10,489 dead, while 16,621 other people are still missing. In addition to some 240,000 refugees at 1,900 evacuation centers due to the disaster, which is the worst crisis in Japan following World War II. When the level was known as a potential threat to sea with 1,250 times more radioactivity than the legal limit, the spokesman for Japan's nuclear safety agency and confirmed that it was a level "relatively high".

Besides water pollution, radiation leaks as a result of problems at the plant have contaminated water, vegetables and milk in neighboring prefectures, what has led many countries to ban imports of products of the area. The measurements provided by Tokyo Electric Power (TEPCO), the company that operates Fukushima, representing a significant increase in radiation in sea water compared to those made on Tuesday, when the level of iodine-131 was 126 times the legal limit, and Thursday, when it was 145 times higher.

Were carried out to 330 yards offshore. Of the three injured workers reactor operators have been hospitalized 3 that came in contact with radioactive water at a level 10,000 times higher than normal, and two of them were admitted. In its latest press on the situation in Fukushima, the IAEA has indicated that the two employees admitted "has been confirmed widespread contamination of the skin on my legs." The two workers received doses of between 2 and 6 sieverts (2000-6000 millisievert), levels that can be fatal.

However, the IAEA states that "even if patients do not need medical treatment, doctors have decided to keep them in the hospital to continue to improve over the coming days." Danger in the direct consumption drinking a pint of fresh water with the current level of radioactivity a person expose the maximum allowed in one year, Nishiyama, who denied that the contamination poses a threat to marine life and safety fish consumption.

"Generally speaking, the released radioactive material is dispersed by ocean currents, and it would take much longer for algae and marine life will absorb," he said. He said that since the time when radioactive iodine is reduced by half is eight days, "when people eat seafood, the amounts will probably decreased significantly." However, TEPCO said the levels of cesium 137, which has a cycle of reduction of some 30 years, were 79.6 times the legal limit.

The government said 30 kilometers from the coast, iodine-131 levels were within acceptable limits. Although the words of Nishiyama try to send a message of reassurance to the public, the announcement of increased radioactivity in the sea will probably cause a new international alert. Several countries, including United States, Australia, Singapore and Russia, have banned the import of food from nearby prefectures Fukushima I, were detected after high doses of radiation in milk and a dozen types of vegetables in this area .

Some governments have already put under surveillance on imports of Japanese seafood, measures are now likely to intensify. Attempts to stabilize the reactor at the plant, technicians continued to work to stabilize the reactor, after suspicions emerged last Friday that the unit 3-for a total of six, could have suffered a crack.

The nuclear safety agency said yesterday that the temperature and pressure in all the reactors have been stabilized. For days after they have been sprayed with sea water to lower the temperature, which would be at the origin of the current water pollution, the engineers have begun to pump fresh water to avoid the corrosive effects of salt water.

The United States has sent two boats with water from one of its naval bases near Tokyo. In the Northeast, rescuers are still searching for bodies in the devastation caused by the earthquake and tsunami, while more than 250,000 people remain in camps. However, the distribution of aid and food and electricity services have improved.

In Tokyo, life has largely returned to normal, although some Japanese and foreigners are still in the south of the country or abroad. Supermarkets are still problems with mineral water, as the population has dominated time after detection bottles tap water in the capital of radiation levels above the allowable for babies.
