Is the Chernobyl reactor explosion, which occurred in the Soviet Union in 1986, the worst nuclear accident at all, since the beginning of use of nuclear energy for industrial purposes in 1940. Inkjet reactor exploding about seven tons of radioactive material in large areas of the world,
The most affected cities, the Soviet city of Kiev and their relevance to the warnings too late, injuring a large number of inhabitants severe burns and has not delivered the whole of Europe from radioactive contamination, increasing the proportion of radioactive contamination in some parts of East Germany 100 times the natural rate, while in Poland amounted to 500 times
The result was the indirect ten thousand cases of cancer in the Soviet Union, and a thousand other case in Europe
Let's look at what happened on the near
Station
Chernobyl plant is located in the village of Pripyat, Ukraine, 18 kilometers north west of Chernobyl, some 16 kilometers from the border with Belarus, Ukraine, and one hundred and ten kilometers north of Kiev.
Station consists of four reactors, each with a capacity to generate a thousand megawatts of electricity. The station produces 10% of the electricity needed by Ukraine as a whole. The construction of the station in 1977 and was completed by adding the fourth reactor built in 1983
Later began to build two others, but the incident has already completed construction
Station is one of the largest power plants in the former Soviet Union
Accident
Saturday 26 April 1986, at first twenty-three minutes and fifty-eight seconds that morning, the fourth reactor exploded
Attributed the explosion to a defect in the design of the reactor, and the errors made by its workers, who allegedly violated safety procedures are supposed to follow. It was also said that the reactor operators had not received adequate training. Another reason is the lack of communication between the operators and security officers
The operators are conducting an experiment during the night, and were not sufficiently aware of some of the characteristics of the reactor, which was kept military secrets
Immediate results
Two hundred and three people were treated in hospitals after the accident, 31 of them died later as a result of radiation exposure. Most of them were workers who were trying to control the situation after the explosion, and who did not warn the seriousness of the situation, or equipped with the necessary equipment
135 thousand have been evacuated people from surrounding areas, including 50 thousand people are residents of the town near the Ukrainian Bibiat.
Spread of radioactive material at random according to the state air. Belarus received about 60% of the quantity leaked. Contamination occurred also in the north-west of Ukraine and a large part of southern Russia, Bryansk
Has been saved the disaster break in the beginning. The day after the disaster for the workers observed in the Forsmark nuclear plant on the 1100-km in Sweden, the presence of radioactive particles on their clothes. Been examined the station and make sure that there was no radiation leak. This was the first reference to the nuclear problem in the Soviet Union
In January 1993, the Commission re-evaluate the incident, concluded that the accident was caused by an error in the design of the reactor and not an error in the operation, while in 1986 the Commission had concluded that the accident caused by an error in the operation. The report said the reactor, contains 190 metric tons of uranium dioxide, the amount of leakage is between 13 to 30% of the quantity
The incident attracted international attention to the need for further action to secure nuclear power plants around the world. Increased public awareness of the public about the dangers of nuclear energy. Has provided foreign governments and international organizations, a lot of assistance for the control of the situation
Increased Altheuerid hormone (thyroid hormone) has a lot of children in the region as a result of exposure to drinking milk contaminated with radioactive iodine. There were also cases of thyroid cancer in many of the children under the age of fourteen in Belarus, Ukraine and Russia. The number of these cases later by 1800 children
Shortly after the incident, there was interest contamination with radioactive iodine, which has a half-life estimated at eight days. Turning attention next to the contamination of soil radioactivity Balstranhim 90 and cesium-137, both of which have a half-life for 30 years and this means that the land needs to thirty years to get rid of half the amount of radioactive material by, and then to thirty more years to get rid of half the remaining half of the radioactive material, and so on
Found the highest concentration of radioactive cesium in the surface layers of the soil, this means that the plants cultivated in the region, in addition to mushrooms, which go in the diet of the population, may have absorbed part of the radioactive material has become contaminated with radioactive
Caused by the Chernobyl explosion of a quantity of radioactive contamination is estimated at about 400 times the pollution caused by the Hiroshima bomb
Dead plants in over ten kilometers around the reactor, including a forest full of pine trees on an area of four square kilometers, as a result of radioactive nuclear fallout, which has spread in the region. After the incident days later the forest trees were glowing red in the strange phenomenon caused by the radioactivity
About a month after the incident, the place was devoid of all traces of life, have been evacuated 116 thousand people in a radius of 30 kilometers around the reactor
After the evacuation of the place, turning into something like a natural reserve for plants and animals! The response of animals to radiation on the human response, the response also varies from species to another. Emerged later reports of the emergence of exotic forms of plant life, it is likely that plants exposed to a number of mutations in the genetic material, as animals emerged distorted alien, which some are calling for the release of the name
"Forest of wonders"
The place
What to do radiation on the human body?
Exposure to radiation for various forms of infection by the dose that is exposed. Exposure leads to the amount of radiation the value of more than 40 Gray (unit of measurement of radiation) to destroy the blood vessels, and thus cerebral edema (fluid accumulation in the tissues of the brain), and then shock and death within 48 hours
Exposure to doses of 10 to 40 Gray lead to less damage to blood vessels, but produce a state of imbalance between the fluid and salts in the body, and the total destruction of the bone marrow, leading to death within ten days
Exposure to doses of 1.5 to 10 Gy lead to inhibition of bone marrow and bleeding. Death occurs most often in the course of five weeks. Can be cured in this case only if treatment is started immediately, without delay, while the higher doses there is no escape from death of them.
Exposure to doses less than this leads to localized tissue damage, may lead to the death of some of these tissues and therefore "Ganjerina" that require limb amputation. And exposure to the general incidence of the disease, which appears after a longer period of time, cancer
The reactor after the accident
Did not stop work on the Chernobyl explosion, which happened in the fourth reactor, the Ukrainian government continued to run the other three reactors, because of the acute shortage of energy suffered by the country. In 1991 a fire broke out in Reactor No. 2 and the damage was beyond repair. In 1996 the third reactor has been closed under an agreement between the Ukrainian Government and the International Atomic Energy Agency
In November 2000, the President of Ukraine "Leonid Kuchma" to close the third reactor itself in an official ceremony, and so the station was closed permanently
