Detailed explanation-1: -The Chernobyl disaster occurred when technicians at nuclear reactor Unit 4 attempted a poorly designed experiment. They shut down the reactor’s power-regulating system and its emergency safety systems, and they removed control rods from its core while allowing the reactor to run at 7 percent power.
Detailed explanation-2: -What caused the Chernobyl accident? On April 26, 1986, the Number Four RBMK reactor at the nuclear power plant at Chernobyl, Ukraine, went out of control during a test at low-power, leading to an explosion and fire that demolished the reactor building and released large amounts of radiation into the atmosphere.
Detailed explanation-3: -However, the psychological effects of Chernobyl remain widespread and profound resulting in suicides, alcohol abuse and apathy. Most emergency workers and people living in contaminated areas received relatively low whole-body radiation doses, according to a United Nations study published in 2008.
