In this 1986 aerial view of the Chernobyl nuclear plant in Chernobyl, Ukraine shows damage from an explosion and fire in reactor four on April 26, 1986 that sent large amounts of radioactive material into the atmosphere. Only three Tass photographers were allowed in — Volodymyr Repik, Igor Kostin and Valery Zufarov. Two later died of radiation-related illnesses, and Kostin suffered from the effects for decades before dying in a car accident in 2015. (AP Photo/Volodymyr Repik)
