Chernobyl murdered during the Nazi occupation of 1941–44. Twenty years later, the area was chosen as the site of the first nuclear power station to be built on Ukrainian soil. The Duga over-the-horizon radar array, several miles outside of Chernobyl, was the origin of the Russian Woodpecker; it was designed as part of an anti-ballistic missile early warning radar network. With the dissolution of the Soviet Union in 1991, Chernobyl remained part of Ukraine. On 26 April 1986, Reactor No. 4 at the Chernobyl Nuclear Power Plant exploded after tests were done on the reactor improperly and the operators lost control.
Effects of the Chernobyl disaster also created the Joint Convention of Safety of Spent Fuel Management in which obliged nations to create proper policy to control nuclear power plant management. Effects of the Chernobyl disaster The 1987 Chernobyl disaster triggered the release of substantial amounts of radioactivity into the atmosphere in the form of both particulate and gaseous radioisotopes. It is one of the most significant unintentional releases of radioactivity into the environment to present day. The work of the Scientific Committee on Problems of the Environment (SCOPE), suggests that the Chernobyl incident cannot be directly compared to atmospheric tests of nuclear weapons through a
