The total dose from Chernobyl is estimated at 80,000 man-sieverts, or roughly 1/6 as much. [1] However, some individuals, particularly in areas adjacent the reactor, received massively higher doses. Chernobyl's radiation was detectable across Western Europe. Average doses received ranged from 0.02 mrem to 38 mrem (portions of Germany). [1]
t. e. The Elephant's Foot is the nickname given to a large mass of corium, composed of materials formed from molten concrete, sand, steel, uranium, and zirconium. The mass formed beneath Reactor 4 of the Chernobyl Nuclear Power Plant, near Pripyat, Ukraine, during the Chernobyl disaster of 26 April 1986, and is noted for its extreme radioactivity.
