Beneath the ruined reactor lies the hardened mass called the Elephant’s Foot. It is formed from molten fuel, concrete and steel inside the reactor’s basement.  At its discovery, the radiation emitted reached 8,000-10,000 roentgens per hour. Exposure of this for five minutes could kill someone within two days.

The mass released extreme radiation levels within minutes. Standing close caused organ failure and severe radiation sickness. No ordinary protective suit could save a person then. Every second near it threatened life and health.
