Beginning in the late 1970s there were unconfirmed reports of an event in the Urals that resulted in widespread contamination of the environs. We now know that this was a chemical explosion in a high level waste storage tank in 1957. This chemical explosion resulted in 20 MCi of radioactive material thrown out from the tank and 2 MCi were dispersed downwind as a plume. This plume contaminated about 23, 000 square kilometers and became known as the "Eastern Urals Radioactive Trace(EURT) ". About 270, 000 persons were exposed and 8, 000 were relocated within periods ranging from 10 to 670 days after the explosion.
