On this day, 39 years ago, on April 26, 1986 (March 18, 1986, the Chernobyl nuclear accident occurred in the Soviet Union. Aerial view of the Chernobyl Nuclear Power Plant after the Accident On April 26, 1986, the world's worst nuclear accident occurred at the Chernobyl Nuclear Power Plant in the Soviet Union. A radioactive leak caused by a catastrophic fire at the Chernobyl nuclear power plant 130 kilometers north of the city of Kiev in Ukraine has contaminated much of Europe, and the international community has widely criticized the Soviet Union's blockade of news of the nuclear accident and its slow emergency response. The accident was exposed to the world after excessive levels of radioactive materials were found in Sweden. The Chernobyl nuclear power plant is the largest nuclear power plant in the former Soviet Union, with a total of four units. In April, during the planned shutdown inspection of Unit 4, the reactor energy increased due to repeated violations of operating procedures by power station personnel. In the early morning of the 26th, the reactor melted and burned, causing an explosion and breaking through the protective shell. The factory caught fire and radioactive materials leaked out. Fighting fires with water and chemicals evaporated instantly, and firefighters 'boots became trapped in the molten asphalt. Units 1, 2 and 3 were suspended, 30 kilometers around the power station were declared a dangerous area, and residents were evacuated. Two people were killed on the spot and 204 people were injured by radiation when the accident occurred. On May 8, the reactor stopped burning and the temperature still reached 300 ° C; the local radiation intensity was up to 15 milliroentgens per hour, and in Kiev City it was 0.2 milliroentgens, while the normal allowable amount was 0.01 milliroentgens. Radioactive dust was detected in Sweden, which was 100 times higher than normal. Western countries rushed to evacuate their expatriates and tourists from the Kiev region and refused to accept imported food from Belarus and Ukraine. Four months later, officials of the former Soviet Union announced that a total of 31 people had died, mainly rescue personnel, including a major general; 203 people suffered from radiation sickness; and 135,000 people were evacuated from dangerous areas. In 1992, Ukraine officially announced that more than 7000 people had died from nuclear pollution in this accident. On May 9, at the invitation of the Soviet government, Blix, Director General of the International Atomic Energy Agency, took a helicopter to inspect the situation of the nuclear power plant from an altitude of 800 meters. He believed that this was by far the most serious nuclear accident in the world. In the two years after the disaster, 260,000 people participated in accident handling, poured layers of concrete on the No. 4 nuclear reactor and buried it as a "coffin." 21 million square meters of "dirty soil" were cleaned, another new city of Slavjec was built for nuclear power plant workers, and another 21,000 houses were built for evacuated residents. All this, including losses from reduced power generation, totaled 8 billion rubles (about 12 billion US dollars). The Ukraine government has made the decision to close the power station forever. The Republic of Belarus has lost 20% of its agricultural land, the land inhabited by 2.2 million people has been polluted, and hundreds of villages and towns have emptied their houses. The abandoned restricted area in Ukraine has become a paradise for thieves and a haven for wild horses. All precious items have been stolen, thus spreading pollution outside the area. Pine trees and spruce trees within 7 kilometers near the nuclear power plant wilted, and 1000 hectares of forest gradually died out. The "safe area" 30 kilometers away is also unsafe, with a sharp increase in cancer patients, child thyroid patients and deformed livestock; Even in a collective farm 80 kilometers away, 20% of piglets were born with abnormal eyes. All of these strange diseases are called "Chernobyl syndrome". Land and water sources were severely polluted, and thousands of people were forced to leave their homes. Chernobyl became a desolate and barren land. Ten years later, radioactivity continues to threaten the lives and health of some 8 million people in Belarus, Ukraine and Russia. Experts say the consequences of the Chernobyl accident will last for a hundred years. Unit 4 was sealed in cement Blix took a helicopter to inspect a lamb rescued from the leak area by nuclear power plant rescue workers and a radiation-affected child being treated in hospital
