On the night of the 25th going into the 26th of April 1986, a chain of events began that would destroy thousands of lives, ruin millions of acres of land and would, in many respects, help catalyst the re-shaping of a world that had been in the grip of the Cold War since 1945. That chain of events would culminate in the nuclear disaster that decimated Reactor 4 at Chernobyl Nuclear Power Plant, near the town of Pripyat, in northern Soviet Ukraine. This April sees the 33rd anniversary of the disaster. Dr. Paul Goldsmith joins Versus History to talk about his research and experiences at Chernobyl.
