Reading up on Russia’s nuclear history is astonishing. They did use dump trucks and and at some point, to solve a problem with rusting steel containers, they just backed the trucks up and dumped radioactive waste straight into a lake. They did that until the lake became highly radioactive. At which point they decided to fill in the lake with dirt and rocks (bury the radiation) until one of their scientists convinced them that doing so would force the radioactive water into the surrounding ground water. So it remains...ahem...a problem. Unbelievable stuff really....but true. There was a chemical explosion at the site (originally believed to have been spontaneous nuclear reaction from just dumping radioactive waste like that - turned out to be chemical explosion though) the force of which blew radioactive material into the surrounding area and knocked down trees (visible on satellite photos) but the Russians say it never happened...
the great atomic lake?
