International Chernobyl Disaster Remembrance Day

Persistent legacy of the Chernobyl disaster : resolution / adopted by the General Assembly. On 26 April 1986 , following a routine 20-second system shut down in Chernobyl Nuclear Power Plant , a surge created a chemical explosion . The accident and the fire that followed released massive amounts of radioactive material into the environment over large parts of the Soviet Union, now the territories of Belarus, Ukraine and the Russian Federation, exposing million of people to radiations. In 2016, the United Nations General Assembly adopted the  resolution A/RES/71/125   designating April 26th as International Chernobyl Disaster Remembrance Day .

The explosion at the Chernobyl Nuclear Power Plant in April 1986 spread a radioactive cloud over large parts of the Soviet Union, now the territories of Belarus, Ukraine and the Russian Federation. Nearly 8.4 million people in the three countries were exposed to radiation. The Soviet Government acknowledged the need for international assistance in 1990. That same year the General Assembly adopted resolution 45/190 , calling for “international cooperation to address and mitigate the consequences at the Chernobyl nuclear power plant.” That was the start of the United Nations’ involvement in the Chernobyl recovery. An Inter-Agency Task Force was established to coordinate the Chernobyl cooperation. In 1991 the UN created the Chernobyl Trust Fund – currently under the management of the Office for the Coordination of Humanitarian Affairs ( OCHA ). Since 1986, the UN family of organizations and major NGOs have launched more than 230 different research and assistance projects in the fields of...

The International Atomic Energy Agency (IAEA) expressed concerns about the dangers of the conflict in the area. On 26 April, IAEA Director General, Rafael Mariano Grossi, headed an expert mission to Ukraine’s Chornobyl Nuclear Power Plant to step up efforts to help prevent the danger of a nuclear accident during the current conflict in the country .

  Chernobyl Nuclear Power Plant , 26 April 1986 – A routine 20-second shut down of the system seemed to be another test of the electrical equipment. But seven seconds later, a surge created a chemical explosion that released nearly 520 dangerous radionuclides into the atmosphere. The force of the explosion spread contamination over large parts of the Soviet Union, now the territories of Belarus, Ukraine and Russia. According to official reports, thirty-one people died immediately and 600,000 “liquidators,” involved in fire-fighting and clean-up operations, were exposed to high doses of radiation. Based on the official reports, nearly 8,400,000 people in Belarus, Russia and Ukraine were exposed to radiation , which is more than the population of Austria. About 155,000 sq. km of territories in the three countries were contaminated, almost half of the total territory of Italy. Agricultural areas covering nearly 52,000 sq. km, which is more than the size of Denmark, were contaminat...

No reports were released until the third day after the Chernobyl explosion . Then, Swedish authorities correlated a map of enhanced radiation levels in Europe with wind direction and announced to the world that a nuclear accident had occurred somewhere in the Soviet Union. Before Sweden’s announcement, the Soviet authorities were conducting emergency fire-fighting and clean-up operations but had chosen not to report the accident or its scale in full. No established legitimate authority was able to immediately address the situation and provide answers to questions such as: Is it safe to leave the house? Is it safe to drink water? Is it safe to eat local produce?  Communicating protective measures early would also have most likely enabled the population to escape exposure to some radionuclides , such as iodine 131 , which are known to cause thyroid cancer. Early evacuation would have helped people avoid the area during the period when iodine 131 is most dangerous, 8-16 days aft...
