When a large meteor enters the Earth’s atmosphere and explodes, this inevitably destroys the ozone layer. It doesn’t represent big threats to the population, however, it should be borne in mind that the flow ultraviolet radiation will increase slightly. Cloudy the weather also does not contribute to the absorption of hard radiation from the sun. In this situation, people with a fair skin type should cut stay outdoors. Meanwhile, the Urals are not discouraged and expect in the evening to see the main astronomical event of the week – span of asteroid 2012 DA14. That’s just as impressive effect is unlikely to succeed. Three Chelyabinsk Region Discovered the place where the wreckage of a meteor exploded over the Urals. Two of they were found in the Chebarkul district of the Chelyabinsk region, one more – in Zlatoust. At the place of impact, the background radiation does not exceed norms. Meanwhile, the first comments by experts on about the Chelyabinsk meteor. According to the RAS, the diameter of the space body exploded in the sky over Chelyabinsk, was a few meters, mass – about ten tons, energy – several kilotons. The body entered the atmosphere at a speed of 15–20 km / s, from the kinetic heating collapsed at heights of 30-50 km.
Further movement of the disintegrated fragments caused a powerful glow and strong shock wave. The bulk of the substance falling body evaporated (burned out), the remaining pieces slowed down and fell to the earth in the form of meteorites. Head of Department, Institute of Astronomy RAS Lidia Rykhlova commented on the event: “The body was quite large, about 10–20 meters in diameter, and it was hard enough, probably iron-nickel, as it could reach the lower layers of the atmosphere, the expert believes. – it melted, partially decayed, but not completely burned into atmosphere, but exploded as a result of heating at some height. That is, almost the same thing happened as in Tunguska in 1908. Only here is a clearer option since the wreckage has already been found. ” Every year, hundreds of large meteors enter the Earth’s atmosphere. But a similar event occurs once every 20-30 years. According to the latest data, the number of victims of the fall of meteorite debris in Chelyabinsk the region has reached thousands of people, a spokeswoman told RIA Novosti Press Center of the Ministry of Internal Affairs of Russia. “According to the latest data, about a thousand people, including more than 200 children, “said interlocutor of the agency. She added that the lake is currently Chebarkul, where, according to preliminary data, a meteorite fell, taken under the protection of police officers.
