22.03.11.Radioaktivnaya dust from emergency plant "Fukushima-1" in Japan has spread eastward, crossed the Pacific, North America and the Atlantic Ocean and reached Iceland.
Number of detected particles of radioactive dust is negligible and, experts say, is not a threat to health.
Presence in the air of particles of radioactive dust — in this case, iodine isotopes — fixed 15 of 65 international dosimetry stations of the Comprehensive Test Ban Treaty.
"The spread of it (radioactive dust) over the Northern Hemisphere — is a matter of just (a few) days," — said a senior researcher at the Institute for Air Research, Norway Andreas Stohl.
According to forecasts of the French agency for nuclear safety, radiation particle concentration level in the air is a thousand times less than after the accident at the Chernobyl nuclear power plant, made in France by 23 March.
Recall, after a massive earthquake and tsunami in Japan on March 11 at the plant "Fukushima-1" has failed and the cooling system, a series of accidents.
At the reactors have been several leaks of radiation, forcing authorities to evacuate people from the 20-kilometer zone around the plant, and to prohibit flying over the station within a radius of 30 kilometers. Later began to appear about finding information in some areas of Japan, radioactive elements, such as isotopes of iodine and cesium in the air, sea and drinking water as well as in food.
