TOKYO, Oct. 18 — RIA Novosti. The new "hot spot" with high background radiation was found in Tokyo's Adachi next to the pool in the primary school, the newspaper "Mainichi" referring to the local authorities.
In the last week is the fourth sluchayobnaruzheniya contamination in residential areas far from emergency plant "Fukushima-1" for more than 200 kilometers. Last Wednesday, there were reports on the identification of strontium on the roof of an apartment house in the city of Yokohama and Tokyo's Setagaya. Later Thursday, the excess radioactivity was detected near Tokyo in Chiba Prefecture in a park in the city Funabashi.
Foci were not detected by experts, and by the people themselves. In many parts of Japan residents to form groups, mostly made up of students and preschool mothers who with dosimeters in the hands literally scour every square inch of the parks and on the streets on the way to school.
At this time, local residents reported to the district administration on a fixed background radiation exceeded once in five points Adachi. Reportedly, household dosimeters recorded from one and up microsieverts of radiation contamination at the school, in the park and other places.
Immediately after received reports from local authorities conducted their own measurements, which showed the level of radiation at the pool in the primary school 3.99 microsieverts per hour at a height of five centimeters of soil. It is noted that the maximum values were recorded near the drainage lines to the engine room pool. Due to the fact that in this area there is no drainage system, excess background radiation may be due to the stagnation of rain water, which could contain radioactive substances.
"We believe that the level of (radioactive contamination) is localized and does not harm human health. However, we consider response options (in this situation) as soon as possible" — the newspaper quoted local administration.
According to the rules set by local authorities, the background radiation should not exceed 0.25 microsieverts per hour.
The area around the pool was fenced. Now experts examined soil samples to the source of radiation.
On other sections reported by local residents, the radiation background was fixed at 0.43 to 0.95 microsieverts per hour, which is also higher than the maximum permissible level.
As a result of what happened on March 11 in the north-east Japan earthquake and 15-meter tsunami on the nuclear power plant "Fukushima-1" has failed cooling system of reactors and pools of spent nuclear fuel. This caused a meltdown of fuel in the three reactors.
Occurred in the first hours and days after the accident, hydrogen explosions leakproof units, resulting in radioactive elements into the atmosphere and water.
For six months after the accident, elevated radiation detected in many kinds of vegetables, mushrooms, meat and milk not only in Fukushima Prefecture, but in remote areas it. All within a radius of 30 kilometers or more from the station were evacuated about 80,000 residents. In late September, the Japanese government abolished the standby for emergency evacuation in a radius of 20 to 30 kilometers from the plant.
