The accident at the Fukushima-1 Nuclear Power Plant was the result of an earthquake of 9.0 magnitude in the Northeastern Japan on March 11, 2011. After the earthquake shocks on the coast, a 14-meter tsunami wave flooded four out of six reactors at the NPP and disabled their cooling system, which led to a series of explosions of hydrogen and core melting.

On November 14, 2013 about 5 tons of metal pipes with extremely high radiation background level were detected on one of the Kiev wholesale scrap metal collection facilities.
