The five most severe man-made disasters in the USSR Bashny.Net

March 13, 1961 Kurenivsko tragedy occurred - a breakthrough dam in Kiev, which killed about 1,500 people. Scientific and technological progress facilitates human life, but also lead to industrial accidents. We will talk about the five most serious accidents in the history of the Soviet Union.

Kurenivsko tragedy

Kurenivsko tragedy took place in Kiev, March 13, 1961. December 2, 1952 it was decided to create a dump of construction waste in the infamous site of Babi Yar. This site overlaps the dam that protects the area from the merge Kurenivka waste from the factories for the production of bricks. March 13 a dam burst and mud wave height of 14 meters flew down the street Teligi. Stream has more power and washed away everything in its path: cars, trams, buildings.

Although the flood, and lasted only half an hour, during which time the wave has had time to carry out waste the lives of hundreds of people and inflict catastrophic damage on the city. The exact number of victims has not been established, but this figure is close to 1, 5 thousand people. Furthermore, it was destroyed approximately 90 buildings, approximately 60 of which were living.

The news of the accident came to the country's population, only 16 of March, and on the day of the tragedy by the authorities, it was decided not to publicize the incident. To do this, all over Kiev were disabled and international long-distance relationship. Later, the expert commission made a decision on the causes of the accident, they were called "error in the project gidrootvalov and dams».



Radiation accident at the factory "Red Sormovo»

Radiation accident at the factory "Red Sormovo", which is located in Nizhny Novgorod, took place January 18, 1970. The tragedy occurred during the construction of the nuclear submarine K-320, which was part of the project "Scat". When the boat was on the stocks, including the reactor suddenly, who worked for 15 seconds at maximum speed for him. As a result, there was radioactive contamination of all machine-assembly department.

At the time of operation of the reactor in the room, there were about 1,000 people working at the plant. Unaware of the infection, the day many had gone home without necessary medical assistance and decontamination treatment. Three of the six victims, brought to a hospital in Moscow, died of radiation sickness. It was decided not to give publicity this incident, and with all those who survived were taken subscription nondisclosure 25 years. It was only the next day after the accident, the workers began to handle. Dealing with the consequences of the accident continued until April 24, 1970, more than a thousand workers of the plant were used in these studies.



The Chernobyl accident

The Chernobyl disaster occurred on 26 April 1986 at the Chernobyl nuclear power plant. The reactor was completely destroyed in the blast, and the environment has been thrown a huge amount of radioactive substances. The accident was the largest in the history of nuclear power. The main factor in affecting the explosion was the radioactive contamination. In addition to areas in the immediate vicinity of the explosion (30 km), the affected areas of Europe. This was due to the fact that the cloud from the explosion, radioactive material blown many kilometers from the source. Loss of radionuclides iodine and cesium were registered on the territory of modern Belarus, Ukraine and the Russian Federation.

During the first three months after the accident killed 31 people, while in the next 15 years from the effects of the accident has killed 60 to 80 people. More than 115 thousand people were evacuated from the 30 km of the affected area. The liquidation of the accident involved more than 600 thousand soldiers and volunteers. The investigation is constantly changing. So far, not exactly set the causes of the accident.



Kyshtym disaster

Kyshtym accident was the first man-made disaster in the Soviet Union, it happened on Sept. 29, 1957. It happened at the plant "Mayak", which was located in a closed military town "Chelyabinsk - 40". Name of the accident received by the closest city Kyshtym.

The cause was an explosion that occurred in a special container for radioactive waste. This container is a flat cylinder, which was made of stainless steel. The design capacity to provide robust, and no one expected that the cooling system fails.

There was an explosion, in which the atmosphere was thrown about 20 million curies of radioactive substances. About 90 percent of the radiation fell on the area of ​​the chemical plant "Mayak". Fortunately, Chelyabinsk-40 was injured. During the liquidation of the accident 23 villages were settled, and the houses themselves, and pets were destroyed.

As a result of the explosion no one was killed. However, the officials who carried out the elimination of the infection, received significant radiation dose. The operation involved about a thousand people. Now, this area is known as the East-Ural radioactive trace, and any economic activity in the area is forbidden.



The disaster at the Plesetsk cosmodrome

March 18, 1980 in preparation for the launch of the carrier rocket "Vostok 2-M" there was an explosion. The incident happened at the Plesetsk cosmodrome. This accident led to a large number of casualties: only in the immediate vicinity of the missile when the explosion was 141 people. 44 people were killed in the fire, the others suffered burns of varying severity and were taken to hospital, four of them subsequently died.

By accident led by the fact that the manufacture of the filter as catalytic materials, hydrogen peroxide was used. Only thanks to the courage of the participants of the accident managed to make a lot of people from the fire. The elimination of the disaster lasted for three days.

In the future, scientists have abandoned the use of hydrogen peroxide as a catalyst, thus avoiding such incidents.

I have everything!
