Tokyo (cnn) - a robot probe found similar conditions of sauna in the No. 2 reactor at the Fukushima Daiichi nuclear power but more low levels of radiation in other damaged units, owner of the mill reported Tuesday.
Reactor No. 2 is supposed to be leaks of water, thousands of tons of which fill the basement of its tunnels of plant and utility of turbine. Workers at the plant began the first of this liquid, highly radioactive contaminated Tuesday water storage tank pumping, nuclear and Industrial Safety Agency announced the Japan. But the Tokyo Electric Power Company, which is the owner of the six-reactor plant, said that he has no idea how much lies in these dark spaces.
Robot inserted into the reactor unit building Monday found up to 41 degrees Celsius (106 F) temperatures and humidity range of 94-99 per cent, Tokyo Electric reported Tuesday. These conditions of fog until the lenses of cameras of the probe, forcing operators to remove the device after a few minutes, said leaders of the society.
But the level of radiation, he recorded was only 4.1 millisieverts per hour - less than 10 per cent of the dose in the buildings of reactor No. 1 and no. 3.
By comparison, the average resident of an industrialized country receives a dose of approximately 3 millisieverts per year. Standards of emergency for plant workers battling the nuclear disaster month limit their annual 250 millisieverts exposure, while a CT scan produced just below 7 and a chest x-ray provides a single dose of words millisieverts 0.05.
Doses greater than 100 millisieverts may increase the long-term risk of cancer, while 1,000 millisieverts can produce irradiation.
Engineers began to deploy the "Packbots" built at the United States in reactors on Sunday. It is part of an effort to get a better view of the conditions inside buildings, where high radiation readings have retained workers for weeks.
Fukushima Daiichi of cooling systems, about 240 km (150 miles) North of Tokyo, were eliminated by the massive tsunami that struck either side of the Pacific of Japan after a huge earthquake on March 11. The disaster caused the nuclear accident since Chernobyl worse as reactors 1-3 cores super-heated and vomies huge amounts of radioactive contamination in the surrounding region.
Reactors 1 and 3 buildings were blown separated by explosions of hydrogen in the early days of the crisis. A further accumulation of hydrogen is supposed to have broken a reservoir of water under the No. 2 reactor and housing pools spend but still energetic fuel assemblies are concerns in units of 1, 3 and 4.
Tokyo Electric this week established a timetable for six to nine months of the end of the crisis and to put the reactors shut down.
The disaster led to mandatory evacuations of about 78,000 people living within 20 km (12.5 miles) from the plant and the commands to people living an another 10 km remain sheltered, affecting a further 60, 000 - more. Several cities inside and outside this RADIUS told to prepare to evacuate quickly, while others have made the difference for additional instructions.
