At the weekend in Russia will have a radioactive cyclone from Japan: experts prepare for the worst

Air flow from Japan can bring to Russia radioactive dust, but the level of concentration will not pose a danger to the public.

However, the worst is still preparing specialists.
"In the Pacific Ocean near Japan formed a shallow cyclone. It will pass through Japan (areas close to Fukushima), and on Saturday evening or at night, this air mass boundary can catch the Southern Kurils, "- said the chief forecaster Sakhalin Lyudmila Alekseeva at a press conference on Friday. On Sunday afternoon, according to her, this mass can affect and Northern Kurils, "Interfax".

"This is a conditional forecast, since no one from the Japanese side we not give any details. Therefore, we calculated the forecast on the basis of a powerful conditional release of radiation from nuclear power plant "Fukushima-1", that is, based on the worst-case scenario. But while these emissions at the plant is not "- said the forecaster.

She also noted that the estimated "Typhoon" (the structure of Hydrometeorology, which makes the spectral analysis of air masses), even on the basis of the worst case scenarios (in the case of a powerful release of radiation at the plant), the concentration of harmful substances in air masses that zadenut Southern and Northern Kuriles, will be 10-12 billion times less than in the area of emission.
We are talking about radioactive iodine, which has a short half-life, explained Alexeev — other radionuclides deposited in the plant and not further distributed. "The trajectory of these air masses is east of the Kuril Islands, during the movement of the clouds are dissipating, and parts of it may reach the Kurils," — she specified.

On Sakhalin, the projections made by the forecasters for the period to 15 April, the trend east-west movement of air masses that come to the island of the Khabarovsk Territory, the Amur region, Yakutia, and the northern part of China. This trend has always acted with respect to smoke, but it was dominated by air masses from China.

As the chief of EMERCOM Teimuraz Kasaev and chief medical officer of the region Darizhapov Boris, who also participated in the press conference, no risk of exceeding the radiation in the Kuriles April 9-10 is not expected, and the reason for concern of the population do not.

EMERCOM going from Friday to strengthen the monitoring of radiation levels in the Kuril Islands, the results of measurements of background radiation (including spectral analysis) will always be brought to the public through the official website of EMERCOM and local media, updated every two hours. A similar monitoring in the Kuril Islands, Sakhalin holds Rospotrebnadzor.

According Darizhapova, Sakhalin and the Kurils by spectral analysis of air, precipitation, sea water (including those from the Pacific Ocean near the South Kuril Islands), fish, ballast water discharged from ships (delivering hydrocarbons to Japan). "No violations were found," — said the chief sanvrach region.

According Darizhapova, in May-June in the region will bring a modern semiconductor spectrometer — a device for measuring the total of all the characteristics of radiation.

Roshydromet: In the Far East of the Russian Federation in the radiation rate

Excess of background radiation in the Russian Far East in connection with the leak of radioactive water at the plant in the Japanese town of Onagawa were observed, reported "Interfax" Roshydromet Friday morning.

"Background radiation in the Far East of the Russian Federation does not exceed the normal values and ranges from 0.08 to 0.15 microsieverts per hour", — the Roshydromet. According to the source, the "threat to the public in connection with a possible leak of radioactive water at the Onagawa nuclear power plant in there."

Roshydromet noted that the situation is being monitored every hour, measure the level of radiation of more than 90 posts located at various points in the region, including Vladivostok and Sakhalin. "We work in the best possible mode, regularly monitor the situation," — added to the department.
