A band of Russian soldiers who bunked in the "Red Forest" - which which got its name due to the horrendous levels of nuclear material left by the Chernobyl nuclear disaster - were "too thick" to realise they were putting themselves at risk of radition poisoning.
On April 26, 1986, Chernobyl's Reactor Number Four exploded - triggering an unprecedented nuclear disaster and dispersing deadly radioactive material into the atmosphere and surrounding area.
Some of the worst affected areas were the immediate surrounds, including the Red Forest - which sits within a six-mile radius of the reactor.
