Evacuee workers in the reactor 2, which has increased radioactivity

Tokyo Electric Power (TEPCO) has indicated that water from the underground floors of the turbine building of unit 2 of Fukushima a radioactivity was detected 10 million times higher than normal. This has forced the company to evacuate workers, according to news agency reported Jiji. In the water of unit 2 concentrations have been recorded more than 1,000 milisiervert per hour, the local agency Kyodo reported.

According to experts consulted by the public broadcaster NHK, in that reactor could be a leak of radioactive material from the nucleus, which has gone abroad since the suppression pool at the base of reactor. For its part, the International Atomic Energy Agency (IAEA) announced that the Fukushima reactor 1 also shows levels of iodine 131, cesium 134 and cesium-137 comparable to the zone of reactor 3, where several workers were injured on Friday .

These three workers came into contact with radioactive water at a level 10,000 times higher than normal, and two of them were hospitalized. In its latest press on the situation in Fukushima, the IAEA 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." While the level of radioactive iodine in the coastal waters near nuclear power rose to a concentration 1,850 times higher than the legal limit, according to the Nuclear Security Agency of Japan.

This implies a further increase of radioactive material in the seawater near the plant, after the authorities announced on Saturday a concentration 1,250 times higher than allowed. The radiation level at that point, 330 meters south of the drainage water reactors 1 to 4, has grown rapidly in recent days compared to previously collected data.

TEPCO, the company operating the nuclear plant, planned to draw water contaminated with radiation of the four blocks Fukushima reactor 1, because it avoids the repair work and radiated several workers. In the four most affected reactors, the water reaches up to one meter in height. During this weekend, the work also focused on injecting fresh water into the reactor affected.

As reported by the NISA, over on Sunday will try to use more powerful pumps. At first, in the reactors and spent fuel pools of salt water was pumped. However, some experts fear that dust and salt can be deposited between the fuel rods thus preventing cooling. So now you try to pump as much freshwater.
