Approximately 30 people died from immediate blast trauma and acute radiation syndrome (ARS) in the seconds to months after the Chernobyl disaster in April 1986.
Eight months after the nuclear accident, workers made a surprising discovery.
When they entered a corridor below the damaged No. 4 reactor, they found a a black, lava-like substance flowing from the reactor core, resembling a man-made volcano.
Among these hardened masses, one stood out, and the crew gave it the nickname "Elephant's Foot" because of its resemblance to the foot of the large mammal.
Elephant's Foot is a solid mass of melted nuclear fuel mixed with concrete, sand and core sealing material.
At the time of its discovery, Elephant's Foot was emitting approximately 8,000 to 10,000 roentgens, or 80 to 100 grays, per hour, delivering a lethal dose of radiation (4.5 grays) within just five minutes.
