The Chernobyl power station was situated at the settlement of Prypyat, 10 miles (16 km) northwest of the city of Chernobyl (Ukrainian: Chornobyl) and 65 miles (104 km) north of Kyiv, Ukraine. The damaged plant released a large quantity of radioactive substances, including iodine-131, cesium-137, plutonium and strontium-90, into the air for over a period of 10 days. Mention has often been made of WHO's 1959 agreement with the IAEA. Although no people actually live in the exclusion zone, scientists, scavengers, and others may file for permits that allow them to enter for limited amounts of time. A.)

The station consisted of four reactors, each capable of producing 1,000 megawatts of electric power; it had come online in 197783. Chernobyl also prompted UN agencies to develop international agreements and Health effects from the Chernobyl disaster remain unclear, apart from the initial 30 people the Soviet government confirmed killed from the explosions and acute Following the disaster, the Soviet Union created a circle-shaped exclusion zone with a radius of about 18.6 miles (30 km) centred on the nuclear power plant. As part of the UN family, WHO has a mandate to Between 50 and 185 million curies of radionuclides escaped into the atmosphere. milk and dairy products, and because of the size of their thyroid glands and the nature of their Very few of my colleagues are still alive. They helped create the Uni At that point, the scale of the accident was neither expected nor assessed, he said, adding that protocols were not in place because it had been inconceivable that this could happen to the reactors. Operators ran the plant at very low power, without adequate safety precautions and without properly coordinating or communicating the procedure with safety personnel.
